Definitions
- the present invention relates generally to network monitoring, and more particularly, but not exclusively, to monitoring networks in a distributed network monitoring environment.
- OSI Open Systems Interconnection
- IP Internet Protocol
- TCP/IP Transmission Control Protocol/Internet Protocol
- the TCP/IP model is similar to the OSI model except that it defines four layers instead of seven.
- the TCP/IP model's four layers for network communication protocol are arranged in the following order: Link (1), Internet (2), Transport (3), and Application (4).
- Link (1) Link (1)
- Internet (2) Internet (2)
- Transport (3) Transport (3)
- Application (4) Application (4)
- the TCP/IP model collapses the OSI model's Application, Presentation, and Session layers into its Application layer.
- the OSI's Physical layer is either assumed or is collapsed into the TCP/IP model's Link layer.
- TCP/IP model versus the OSI model
- both of these models describe stacks that include basically the same protocols.
- the TCP protocol is listed on the fourth layer of the OSI model and on the third layer of the TCP/IP model.
- packet sniffer may be employed to generally monitor and record packets of data as they are communicated over a network.
- Some packet sniffers can display data included in each packet and provide statistics regarding a monitored stream of packets.
- program analyzers some types of network monitors are referred to as “protocol analyzers” in part because they can provide additional analysis of monitored and recorded packets regarding a type of network, communication protocol, or application.
- packet sniffers and protocol analyzers passively monitor network traffic without participating in the communication protocols. In some instances, they receive a copy of each packet on a particular network segment or VLAN from one or more members of the network segment. They may receive these packet copies through a port mirror on a managed Ethernet switch, e.g., a Switched Port Analyzer (SPAN) port, a Roving Analysis Port (RAP), or the like, or combinations thereof.
- Port mirroring enables analysis and debugging of network communications. Port mirroring can be performed for inbound or outbound traffic (or both) on single or multiple interfaces.
- packet copies may be provided to the network monitors from a specialized network tap or from a software entity running on the client or server.
- port mirroring may be performed on a virtual switch that is incorporated within the hypervisor.

- the term “or” is an inclusive “or” operator, and is equivalent to the term “and/or,” unless the context clearly dictates otherwise.
- the term “based on” is not exclusive and allows for being based on additional factors not described, unless the context clearly dictates otherwise.
- the meaning of “a,” “an,” and “the” include plural references.
- the meaning of “in” includes “in” and “on.”
- engine refers to logic embodied in hardware or software instructions, which can be written in a programming language, such as C, C++, Objective-C, COBOL, JavaTM, PHP, Perl, JavaScript, Ruby, VBScript, Microsoft .NETTM languages such as C#, or the like.
- An engine may be compiled into executable programs or written in interpreted programming languages.
- Software engines may be callable from other engines or from themselves.
- Engines described herein refer to one or more logical modules that can be merged with other engines or applications, or can be divided into sub-engines.
- the engines can be stored in non-transitory computer-readable medium or computer storage device and be stored on and executed by one or more general purpose computers, thus creating a special purpose computer configured to provide the engine.
- the term “session” refers to a semi-permanent interactive packet interchange between two or more communicating endpoints, such as network devices.
- a session is set up or established at a certain point in time, and torn down at a later point in time.
- An established communication session may involve more than one message in each direction.
- a session may have stateful communication where at least one of the communicating network devices saves information about the session history to be able to communicate.
- a session may also provide stateless communication, where the communication consists of independent requests with responses between the endpoints.
- An established session is the basic requirement to perform a connection-oriented communication.
- a session also is the basic step to transmit in connectionless communication modes.
- connection refers to communication sessions with a semi-permanent connection for interactive packet interchange between two or more communicating endpoints, such as network devices.
- the connection may be established before application data is transferred, and where a stream of data is delivered in the same or different order than it was sent.
- the alternative to connection-oriented transmission is connectionless communication.
- IP Internet Protocol
- UDP Universal Datagram Protocol
- IP Internet Protocol
- UDP Universal Datagram Protocol
- Packets associated with a TCP protocol connection may also be routed independently and could be delivered over different paths.
- the network communication system may provide the packets to application endpoints in the correct order.
- Connection-oriented communication may be a packet-mode virtual circuit connection.
- a transport layer virtual circuit protocol such as the TCP protocol can deliver packets of data in order although the lower layer switching is connectionless.
- a connection-oriented transport layer protocol such as TCP can also provide connection-oriented communications over connectionless communication. For example, if TCP is based on a connectionless network layer protocol (such as IP), this TCP/IP protocol can then achieve in-order delivery of a byte stream of data, by means of segment sequence numbering on the sender side, packet buffering and data packet reordering on the receiver side.
- IP connectionless network layer protocol
- the virtual circuit connection may be established in a datalink layer or network layer switching mode, where all data packets belonging to the same traffic stream are delivered over the same path, and traffic flows are identified by some connection identifier rather than by complete routing information, which enables fast hardware based switching.
- the terms “session flow” and “network flow” refer to one or more network packets or a stream of network packets that are communicated in a session that is established between at least two endpoints, such as two network devices.
- flows may be useful if one or more of the endpoints of a session may be behind a network traffic management device, such as a firewall, switch, router, load balancer, or the like.
- a network traffic management device such as a firewall, switch, router, load balancer, or the like.
- such flows may be used to ensure that the packets sent between the endpoints of a flow may be routed appropriately.
- establishing a TCP based connection between endpoints begins with the execution of an initialization protocol and creates a single bi-directional flow between two endpoints, e.g., one direction of flow going from endpoint A to endpoint B, the other direction of the flow going from endpoint B to endpoint A, where each endpoint is at least identified by an IP address and a TCP port.
- protocols or network applications may establish a separate flow for control information that enables management of at least one or more flows between two or more endpoints.
- network flows may be half-flows that may be unidirectional.
- tuple refers to a set of values that identify a source and destination of a network packet, which may, under some circumstances, be a part of a network connection.
- a tuple may include a source Internet Protocol (IP) address, a destination IP address, a source port number, a destination port number, virtual LAN segment identifier (VLAN ID), tunnel identifier, routing interface identifier, physical interface identifier, or a protocol identifier. Tuples may be used to identify network flows (e.g., connection flows).
- IP Internet Protocol
- VLAN ID virtual LAN segment identifier
- Tuples may be used to identify network flows (e.g., connection flows).
- related flows are network flows that while separate they are operating cooperatively.
- some protocols such as, FTP, SIP, RTP, VOIP, custom protocols, or the like, may provide control communication over one network flow and data communication over other network flows.
- configuration rules may define one or more criteria that are used to recognize that two or more network flows should be considered related flows. For example, configuration rules may define that flows containing a particular field value should be grouped with other flows having the same field value, such as, a cookie value, or the like.
- the terms “network monitor”, “network monitoring computer”, or “NMC” refer to an application (software, hardware, or some combination) that is arranged to monitor and record flows of packets in a session that are communicated between at least two endpoints over at least one network.
- the NMC can provide information for assessing different aspects of these monitored flows.
- the NMC may passively monitor network packet traffic without participating in the communication protocols. This monitoring may be performed for a variety of reasons, including troubleshooting and proactive remediation, end-user experience monitoring, SLA monitoring, capacity planning, application lifecycle management, infrastructure change management, infrastructure optimization, business intelligence, security, and regulatory compliance.
- the NMC can receive network communication for monitoring through a variety of means including network taps, wireless receivers, port mirrors or directed tunnels from network switches, clients or servers including the endpoints themselves, or other infrastructure devices.
- the NMC may receive a copy of each packet on a particular network segment or virtual local area network (VLAN). Also, for at least some of the various embodiments, they may receive these packet copies through a port mirror on a managed Ethernet switch, e.g., a Switched Port Analyzer (SPAN) port, a Roving Analysis Port (RAP), or the like, or combination thereof.
- Port mirroring enables analysis and debugging of network communications. Port mirroring can be performed for inbound or outbound traffic (or both) on single or multiple interfaces.
- the NMC may track network connections from and to end points such as a client or a server.
- the NMC may also extract information from the packets including protocol information at various layers of the communication protocol stack.
- the NMC may reassemble or reconstruct the stream of data exchanged between the endpoints.
- the NMC may perform decryption of the payload at various layers of the protocol stack.
- the NMC may passively monitor the network traffic or it may participate in the protocols as a proxy.
- the NMC may attempt to classify the network traffic according to communication protocols that are used.
- the NMC may also perform one or more actions for classifying protocols that may be a necessary precondition for application classification. While some protocols run on well-known ports, others do not. Thus, even if there is traffic on a well-known port, it is not necessarily the protocol generally understood to be assigned to that port. As a result, the NMC may perform protocol classification using one or more techniques, such as, signature matching, statistical analysis, traffic analysis, and other heuristics. In some cases, the NMC may use adaptive protocol classification techniques where information used to classify the protocols may be accumulated or applied over time to further classify the observed protocols. In some embodiments, NMCs may be arranged to employ stateful analysis.
- an NMC may use network packet payload data to drive a state machine that mimics the protocol state changes in the client/server flows being monitored.
- the NMC may categorize the traffic where categories might include file transfers, streaming audio, streaming video, database access, interactive, gaming, and the like.
- the NMC may attempt to determine whether the traffic corresponds to known communications protocols, such as HTTP, FTP, SMTP, RTP, TDS, TCP, IP, and the like.
- NMCs or NMC functionality may be implemented using hardware or software based proxy devices that may be arranged to intercept network traffic in the monitored networks.
- layer and “model layer” refer to a layer of one or more communication protocols in a stack of communication protocol layers that are defined by a model, such as the OSI model and the TCP/IP (IP) model.
- the OSI model defines seven layers and the TCP/IP model defines four layers of communication protocols.
- bits are communicated between computing devices over some type of media, such as cables, network interface cards, radio wave transmitters, and the like.
- Data Link bits are encoded into packets and packets are also decoded into bits.
- the Data Link layer also has two sub-layers, the Media Access Control (MAC) sub-layer and the Logical Link Control (LLC) sub-layer.
- the MAC sub-layer controls how a computing device gains access to the data and permission to transmit it.
- the LLC sub-layer controls frame synchronization, flow control and error checking.
- Network logical paths are created, known as virtual circuits, to communicated data from node to node. Routing, forwarding, addressing, internetworking, error handling, congestion control, and packet sequencing are functions of the Network layer.
- Transport transparent transfer of data between end computing devices, or hosts, is provided. The Transport layer is responsible for end to end recovery and flow control to ensure complete data transfer over the network.
- the Session layer sets up, coordinates, and terminates conversations, exchanges, and dialogues between applications at each end of a connection.
- the Session layer sets up, coordinates, and terminates conversations, exchanges, and dialogues between applications at each end of a connection.
- independence from differences in data representation, e.g., encryption is provided by translating from application to network format and vice versa.
- the Presentation layer transforms data into the form that the protocols at the Application layer (7) can accept.
- the Presentation layer generally handles the formatting and encrypting/decrypting of data that is communicated across a network.
- the Application layer provides services for file transfer, messaging, and displaying data.
- Protocols at the Application layer include FTP, HTTP, and Telnet.
- the TCP/IP model collapses the OSI model's Application, Presentation, and Session layers into its Application layer. Also, the OSI's Physical layer is either assumed or may be collapsed into the TCP/IP model's Link layer. Although some communication protocols may be listed at different numbered or named layers of the TCP/IP model versus the OSI model, both of these models describe stacks that include basically the same protocols.

- FIG. 11 illustrates a logical representation of a data structure for device relation model 1100 that includes entities in accordance with the one or more embodiments.
- network monitoring computers NMCs
- device relation model 1100 represents the entities discovered network 1000 shown in FIG. 10 .
- NMCs may arrange device relation models to represent the relationship the entities have to each other rather than just modeling the network topology.
- entity 1106 , entity 1110 , and entity 1118 are each related to the DNS system in network 1000 . Therefore, in this example, for some embodiments, the NMC may arrange device relation model 1100 such that all of the DNS related entities (entity 1106 , entity 1110 , and entity 1118 ) are neighbors in the graph. Accordingly, in some embodiments, even though entity 1106 corresponds to DNS client 1006 on client computer 1002 , the NMC may group entity 1106 with the other DNS entities rather than put it next other entities in the same computer.
- the NMC may be arranged to generate device relation model 1100 based on the relationships that the entities have with each other. Accordingly, in some embodiments, the edges in the graph may be selected or prioritized (e.g., weighted) based on the type or strength of the relationship. In at least one of the various embodiments, the metrics used for prioritizing the edges in a device relation model may be selected/computed based on configuration information that includes rules, conditions, pattern matching, scripts, computer readable instructions, or the like. In some embodiments, NMCs may be arranged to apply this configuration information to the observed network packets (e.g., headers, payloads, or the like) to identify and evaluate relationships.
- the observed network packets e.g., headers, payloads, or the like
- the edge connecting entity 1104 and entity 1108 is depicted thicker to represent the close relationship the web server entity has with the database client entity. This reflects that the web server may be hosting a data centric web application that fetches data from a database when it receives HTTP requests from clients.
- the relationship between the database client (entity 1108 ) and the database server (entity 1112 ) is also a strong relationship.
- the relationship between the authorization client (entity 1114 ) and the authorization server (entity 1116 ) is a strong relationship.
- the client (entity 1102 ) and DNS client 1 (entity 1106 ) have a strong relationship and it follows that DNS client 1 (entity 1106 ) has a strong relationship with the DNS server (entity 1118 ).
- DNS client 2 (entity 1110 ) has a weak relationship with the DNS server (entity 1118 ). In this example, this may make sense because DNS client 1 (entity 1106 ) is often used by the client (entity 1102 ) to send lookup requests to the DNS server.
- DNS client 2 (entity 1110 ) is rarely used since it is running on the server computer (server computer 1008 in FIG. 10 ) and it may rarely issue name lookup requests.
- the NMC may traverse device relation model 1100 to identify entities that may be closely related together and associate them into a group. For example, in some embodiments, in device relation model 1100 , entity 1104 , entity 1108 , and entity 1112 may be grouped since they each have strong relationships with each other.
- the NMC may be arranged to correlate error signals that may be associated with one or more entities that are in the same group to determine that an anomaly may be occurring.
- Related error signals that may propagate through a group of closely related entities may be recognized as a bigger problem that rises to an actual anomaly.

- the NMC may be arranged to capture/monitor incoming and outgoing network traffic for entities in a monitored network.
- the NMC may be arranged to employ various protocol analysis facilities, such as, state machines, mathematical models, or the like, to track expected/normal operations of different types of entities in a monitored network.
- the NMC may monitor the state of operations for entities that are working together. For example, a web client entity, such as, entity 1102 , may make an HTTP request to web server entity 1104 , that in turn triggers the web server entity 1104 to issue a database request to DB client entity 1108 that in turn is provided database server entity 1112 .
- the NMC may monitor the operation of each entity in the group by observing the network traffic exchanged between the entities in a group.
- the NMC may be able to correlate the error at database server entity 1112 with the “timeout” error at web client entity 1102 to recognize what may be a serious anomaly.
- FIG. 12 represents a logical representation of system 1200 for transforming monitored network traffic into anomaly profile objects (e.g., anomaly profiles) or investigation profile objects (e.g., investigation profiles) in accordance with one or more of the various embodiments.

- anomaly profiles may include collections of one or more fields with values that may be based on network traffic 1204 or metrics associated with network traffic 1202 .
- one or more of the metrics included in an anomaly profile may correspond to metrics collected by the NMC.
- one or more of the metrics included in an anomaly profile may be composed of two or more metrics.
- one or more metrics or features of an anomaly profile may be computed based on one or more observed metrics.
- metric values included in anomaly profiles may be normalized or fit to a common schema as well as arithmetically normalized.

Abstract
Description
- The present invention relates generally to network monitoring, and more particularly, but not exclusively, to monitoring networks in a distributed network monitoring environment.
- On most computer networks, bits of data arranged in bytes are packaged into collections of bytes called packets. These packets are generally communicated between computing devices over networks in a wired or wireless manner. A suite of communication protocols is typically employed to communicate between at least two endpoints over one or more networks. The protocols are typically layered on top of one another to form a protocol stack. One model for a network communication protocol stack is the Open Systems Interconnection (OSI) model, which defines seven layers of different protocols that cooperatively enable communication over a network. The OSI model layers are arranged in the following order: Physical (1), Data Link (2), Network (3), Transport (4), Session (5), Presentation (6), and Application (7).
- Another model for a network communication protocol stack is the Internet Protocol (IP) model, which is also known as the Transmission Control Protocol/Internet Protocol (TCP/IP) model. The TCP/IP model is similar to the OSI model except that it defines four layers instead of seven. The TCP/IP model's four layers for network communication protocol are arranged in the following order: Link (1), Internet (2), Transport (3), and Application (4). To reduce the number of layers from four to seven, the TCP/IP model collapses the OSI model's Application, Presentation, and Session layers into its Application layer. Also, the OSI's Physical layer is either assumed or is collapsed into the TCP/IP model's Link layer. Although some communication protocols may be listed at different numbered or named layers of the TCP/IP model versus the OSI model, both of these models describe stacks that include basically the same protocols. For example, the TCP protocol is listed on the fourth layer of the OSI model and on the third layer of the TCP/IP model. To assess and troubleshoot communicated packets and protocols over a network, different types of network monitors can be employed. One type of network monitor, a “packet sniffer” may be employed to generally monitor and record packets of data as they are communicated over a network. Some packet sniffers can display data included in each packet and provide statistics regarding a monitored stream of packets. Also, some types of network monitors are referred to as “protocol analyzers” in part because they can provide additional analysis of monitored and recorded packets regarding a type of network, communication protocol, or application.
- Generally, packet sniffers and protocol analyzers passively monitor network traffic without participating in the communication protocols. In some instances, they receive a copy of each packet on a particular network segment or VLAN from one or more members of the network segment. They may receive these packet copies through a port mirror on a managed Ethernet switch, e.g., a Switched Port Analyzer (SPAN) port, a Roving Analysis Port (RAP), or the like, or combinations thereof. Port mirroring enables analysis and debugging of network communications. Port mirroring can be performed for inbound or outbound traffic (or both) on single or multiple interfaces. In other instances, packet copies may be provided to the network monitors from a specialized network tap or from a software entity running on the client or server. In virtual environments, port mirroring may be performed on a virtual switch that is incorporated within the hypervisor.
- In complex networks, network activity, investigating performance or activity anomalies may difficult given the complexity and size of contemporary networks. This may result in incident analysts performing ad-hoc actions to resolve or investigate anomalies in the network. Also, in some cases, organizations may provide workflows or playbooks that to help analysts leverage past investigations. However, ensuring the these workflows or playbooks are followed may be difficult. Also, in some cases, it may be difficult for an organization to track which investigation workflows or playbooks may be effective. Thus, it is with respect to these considerations and others that the present invention has been made.

The embodiments may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the embodiments to those skilled in the art. Among other things, the various embodiments may be methods, systems, media or devices. Accordingly, the various embodiments may take the form of an entirely hardware embodiment, an entirely software embodiment or an embodiment combining software and hardware aspects. The following detailed description is, therefore, not to be taken in a limiting sense.
- Throughout the specification and claims, the following terms take the meanings explicitly associated herein, unless the context clearly dictates otherwise. The phrase “in one embodiment” as used herein does not necessarily refer to the same embodiment, though it may. Furthermore, the phrase “in another embodiment” as used herein does not necessarily refer to a different embodiment, although it may. Thus, as described below, various embodiments may be readily combined, without departing from the scope or spirit of the invention.
- In addition, as used herein, the term “or” is an inclusive “or” operator, and is equivalent to the term “and/or,” unless the context clearly dictates otherwise. The term “based on” is not exclusive and allows for being based on additional factors not described, unless the context clearly dictates otherwise. In addition, throughout the specification, the meaning of “a,” “an,” and “the” include plural references. The meaning of “in” includes “in” and “on.”
- For example embodiments, the following terms are also used herein according to the corresponding meaning, unless the context clearly dictates otherwise.
- As used herein the term, “engine” refers to logic embodied in hardware or software instructions, which can be written in a programming language, such as C, C++, Objective-C, COBOL, Java™, PHP, Perl, JavaScript, Ruby, VBScript, Microsoft .NET™ languages such as C#, or the like. An engine may be compiled into executable programs or written in interpreted programming languages. Software engines may be callable from other engines or from themselves. Engines described herein refer to one or more logical modules that can be merged with other engines or applications, or can be divided into sub-engines. The engines can be stored in non-transitory computer-readable medium or computer storage device and be stored on and executed by one or more general purpose computers, thus creating a special purpose computer configured to provide the engine.
- As used herein, the term “session” refers to a semi-permanent interactive packet interchange between two or more communicating endpoints, such as network devices. A session is set up or established at a certain point in time, and torn down at a later point in time. An established communication session may involve more than one message in each direction. A session may have stateful communication where at least one of the communicating network devices saves information about the session history to be able to communicate. A session may also provide stateless communication, where the communication consists of independent requests with responses between the endpoints. An established session is the basic requirement to perform a connection-oriented communication. A session also is the basic step to transmit in connectionless communication modes.
- As used herein, the terms “network connection,” and “connection” refer to communication sessions with a semi-permanent connection for interactive packet interchange between two or more communicating endpoints, such as network devices. The connection may be established before application data is transferred, and where a stream of data is delivered in the same or different order than it was sent. The alternative to connection-oriented transmission is connectionless communication. For example, the datagram mode of communication used by the Internet Protocol (IP) and the Universal Datagram Protocol (UDP) may deliver packets out of order, since different packets may be routed independently and could be delivered over different paths. Packets associated with a TCP protocol connection may also be routed independently and could be delivered over different paths. However, for TCP connections the network communication system may provide the packets to application endpoints in the correct order.
- Connection-oriented communication may be a packet-mode virtual circuit connection. For example, a transport layer virtual circuit protocol such as the TCP protocol can deliver packets of data in order although the lower layer switching is connectionless. A connection-oriented transport layer protocol such as TCP can also provide connection-oriented communications over connectionless communication. For example, if TCP is based on a connectionless network layer protocol (such as IP), this TCP/IP protocol can then achieve in-order delivery of a byte stream of data, by means of segment sequence numbering on the sender side, packet buffering and data packet reordering on the receiver side. Alternatively, the virtual circuit connection may be established in a datalink layer or network layer switching mode, where all data packets belonging to the same traffic stream are delivered over the same path, and traffic flows are identified by some connection identifier rather than by complete routing information, which enables fast hardware based switching.
- As used herein, the terms “session flow” and “network flow” refer to one or more network packets or a stream of network packets that are communicated in a session that is established between at least two endpoints, such as two network devices. In one or more of the various embodiments, flows may be useful if one or more of the endpoints of a session may be behind a network traffic management device, such as a firewall, switch, router, load balancer, or the like. In one or more of the various embodiments, such flows may be used to ensure that the packets sent between the endpoints of a flow may be routed appropriately.
- Typically, establishing a TCP based connection between endpoints begins with the execution of an initialization protocol and creates a single bi-directional flow between two endpoints, e.g., one direction of flow going from endpoint A to endpoint B, the other direction of the flow going from endpoint B to endpoint A, where each endpoint is at least identified by an IP address and a TCP port.
- Also, some protocols or network applications may establish a separate flow for control information that enables management of at least one or more flows between two or more endpoints. Further, in some embodiments, network flows may be half-flows that may be unidirectional.
- As used herein, the term “tuple” refers to a set of values that identify a source and destination of a network packet, which may, under some circumstances, be a part of a network connection. In one embodiment, a tuple may include a source Internet Protocol (IP) address, a destination IP address, a source port number, a destination port number, virtual LAN segment identifier (VLAN ID), tunnel identifier, routing interface identifier, physical interface identifier, or a protocol identifier. Tuples may be used to identify network flows (e.g., connection flows).
- As used herein the term “related flows,” or “related network flows” as used herein are network flows that while separate they are operating cooperatively. For example, some protocols, such as, FTP, SIP, RTP, VOIP, custom protocols, or the like, may provide control communication over one network flow and data communication over other network flows. Further, configuration rules may define one or more criteria that are used to recognize that two or more network flows should be considered related flows. For example, configuration rules may define that flows containing a particular field value should be grouped with other flows having the same field value, such as, a cookie value, or the like.
- As used herein, the terms “network monitor”, “network monitoring computer”, or “NMC” refer to an application (software, hardware, or some combination) that is arranged to monitor and record flows of packets in a session that are communicated between at least two endpoints over at least one network. The NMC can provide information for assessing different aspects of these monitored flows. In one or more embodiment, the NMC may passively monitor network packet traffic without participating in the communication protocols. This monitoring may be performed for a variety of reasons, including troubleshooting and proactive remediation, end-user experience monitoring, SLA monitoring, capacity planning, application lifecycle management, infrastructure change management, infrastructure optimization, business intelligence, security, and regulatory compliance. The NMC can receive network communication for monitoring through a variety of means including network taps, wireless receivers, port mirrors or directed tunnels from network switches, clients or servers including the endpoints themselves, or other infrastructure devices. In at least some of the various embodiments, the NMC may receive a copy of each packet on a particular network segment or virtual local area network (VLAN). Also, for at least some of the various embodiments, they may receive these packet copies through a port mirror on a managed Ethernet switch, e.g., a Switched Port Analyzer (SPAN) port, a Roving Analysis Port (RAP), or the like, or combination thereof. Port mirroring enables analysis and debugging of network communications. Port mirroring can be performed for inbound or outbound traffic (or both) on single or multiple interfaces.
- The NMC may track network connections from and to end points such as a client or a server. The NMC may also extract information from the packets including protocol information at various layers of the communication protocol stack. The NMC may reassemble or reconstruct the stream of data exchanged between the endpoints. The NMC may perform decryption of the payload at various layers of the protocol stack. The NMC may passively monitor the network traffic or it may participate in the protocols as a proxy. The NMC may attempt to classify the network traffic according to communication protocols that are used.
- The NMC may also perform one or more actions for classifying protocols that may be a necessary precondition for application classification. While some protocols run on well-known ports, others do not. Thus, even if there is traffic on a well-known port, it is not necessarily the protocol generally understood to be assigned to that port. As a result, the NMC may perform protocol classification using one or more techniques, such as, signature matching, statistical analysis, traffic analysis, and other heuristics. In some cases, the NMC may use adaptive protocol classification techniques where information used to classify the protocols may be accumulated or applied over time to further classify the observed protocols. In some embodiments, NMCs may be arranged to employ stateful analysis. Accordingly, for each supported protocols, an NMC may use network packet payload data to drive a state machine that mimics the protocol state changes in the client/server flows being monitored. The NMC may categorize the traffic where categories might include file transfers, streaming audio, streaming video, database access, interactive, gaming, and the like. The NMC may attempt to determine whether the traffic corresponds to known communications protocols, such as HTTP, FTP, SMTP, RTP, TDS, TCP, IP, and the like.
- In one or more of the various embodiments, NMCs or NMC functionality may be implemented using hardware or software based proxy devices that may be arranged to intercept network traffic in the monitored networks.
- As used herein, the terms “layer” and “model layer” refer to a layer of one or more communication protocols in a stack of communication protocol layers that are defined by a model, such as the OSI model and the TCP/IP (IP) model. The OSI model defines seven layers and the TCP/IP model defines four layers of communication protocols.
- For example, at the OSI model's lowest or first layer (Physical), streams of electrical/light/radio impulses (bits) are communicated between computing devices over some type of media, such as cables, network interface cards, radio wave transmitters, and the like. At the next or second layer (Data Link), bits are encoded into packets and packets are also decoded into bits. The Data Link layer also has two sub-layers, the Media Access Control (MAC) sub-layer and the Logical Link Control (LLC) sub-layer. The MAC sub-layer controls how a computing device gains access to the data and permission to transmit it. The LLC sub-layer controls frame synchronization, flow control and error checking. At the third layer (Network), logical paths are created, known as virtual circuits, to communicated data from node to node. Routing, forwarding, addressing, internetworking, error handling, congestion control, and packet sequencing are functions of the Network layer. At the fourth layer (Transport), transparent transfer of data between end computing devices, or hosts, is provided. The Transport layer is responsible for end to end recovery and flow control to ensure complete data transfer over the network.
- At the fifth layer (Session) of the OSI model, connections between applications are established, managed, and terminated. The Session layer sets up, coordinates, and terminates conversations, exchanges, and dialogues between applications at each end of a connection. At the sixth layer (Presentation), independence from differences in data representation, e.g., encryption, is provided by translating from application to network format and vice versa. Generally, the Presentation layer transforms data into the form that the protocols at the Application layer (7) can accept. For example, the Presentation layer generally handles the formatting and encrypting/decrypting of data that is communicated across a network.
- At the top or seventh layer (Application) of the OSI model, application and end user processes are supported. For example, communication partners may be identified, quality of service can be identified, user authentication and privacy may be considered, and constraints on data syntax can be identified. Generally, the Application layer provides services for file transfer, messaging, and displaying data. Protocols at the Application layer include FTP, HTTP, and Telnet.
- To reduce the number of layers from seven to four, the TCP/IP model collapses the OSI model's Application, Presentation, and Session layers into its Application layer. Also, the OSI's Physical layer is either assumed or may be collapsed into the TCP/IP model's Link layer. Although some communication protocols may be listed at different numbered or named layers of the TCP/IP model versus the OSI model, both of these models describe stacks that include basically the same protocols.
- As used herein the term “metric” refers to a value that represents one or more performance characteristics of a monitored network. Metrics may include aggregated measurements, rate of changes, proportions, or the like, Metrics may be associated with particular network application, network protocols, entities, or the like. Metrics may include an indication of the presence of one or more patterns, such as, network packet headers, protocol preambles, or the like. Common metrics may include: requests and responses for Hypertext Transfer Protocol) HTTP; database protocols; Transport Security Layer/Secure Sockets Layer (TLS/SSL); storage protocols, such as, Common Internet File System (CIFS) or Network File System (NFS), Domain Name Service (DNS), Lightweight Directory Access Protocol (LDAP); NoSQL storage protocols such as MongoDB or Memcache, File Transfer Protocol (FTP), Simple Mail Transfer Protocol (SMTP); and Voice-over-IP (VoIP) protocols such as Session Initiation Protocol (SIP) and Real-time Transport Protocol (RTP); or the like. Within each of metric, there may be measurements broken down by Response Status Codes (that may apply across many protocols, including HTTP, SMTP, SIP); HTTP Requests by Method (GET, POST, HEAD, or the like.); requests by SQL method and table, SSL certificate expiration time by host, various protocols by username (e.g., LDAP, FTP, SMTP, VoIP, or the like), and by client or server IP (almost every protocol). Also, in some embodiments, users may define custom metrics based on the collection of user-defined measurements for a given protocol or entity.
- As used herein the “metric visualization,” or “visualization” refers to a graphical representation of one or more metrics. A metric may be associated with one or more different types of visualizations. In some embodiments, metric visualizations may be line graphs, pie charts, bar graphs, scatter plots, heat maps, Sankey diagrams, histograms, time series graphs, candlestick charts, geolocation charts, or the like, or combination thereof, displayed in a graphical user interface.
- As used herein, the term “entity” refers to an actor or element in a monitored network. Entities may include applications, services, programs, processes, network devices, network computers, client computers, or the like, operating in the monitored network. For example, individual entities may include, web clients, web servers, database clients, database servers, mobile app clients, payment processors, groupware clients, groupware services, or the like. In some cases, multiple entities may co-exist on or in the same network computer, process, application, compute container, or cloud compute instance.
- As used herein, the term “device relation model” refers to a data structure that is used to represent relationships between and among different entities in a monitored network. Device relation models may be graph models comprised of nodes and edges stored in the memory of a network computer. In some embodiments, the network computer may automatically update the configuration and composition of the device relation model stored in the memory of the network computer to reflect the relationships between two or more entities in the monitored network.

For example, in some embodiments, a simplified system may include one or more NMCs that also provide capture agent services. In some embodiments, capture agents may be NMCs arranged to instantiate one or more capture engines to perform one or more capture or collection actions. Similarly, in one or more of the various embodiments, one or more capture agents may be instantiated or hosted separately from one or more NMCs.
- In one or more of the various embodiments, capture agents may be selectively installed such that may capture metrics for select portions of the monitored networks. Also, in some embodiments, in networks that have groups or clusters of the same or similar entities, capture agents may be selectively installed on one or more entities that may be representative of entire groups or clusters pf similar entities. Thus, in some embodiments, capture agents on the representative entities may collect metrics or traffic that may be used to infer the metrics or activity associated with similarly situated entities that do not include a capture agent.
- Likewise, in one or more of the various embodiments, one or more capture agents may be installed or activated for a limited time period to collect information that may be used to infer activity information about the monitored networks.

- In one or more of the various embodiments,
system 500 may include one or more network entities, such as,entities 518,entities 520, or the like, that communicate in or over one or more of the monitored networks.Entities 518 andentities 520 are illustrated here as cloud environment compute instances (e.g., virtual machines), or the like.

FIG. 6 illustrates a logical representation ofnetwork 600 in accordance with at least one of the various embodiments. In at least one of the various embodiments, network 602 represents a physical network and the entities in the network. In this example, network 602 includes,network computers 604,client computers 606, network devices, such as,network device 610, and other items, such as, Wi-Fi hotspot 608. One of ordinary skill in the art will appreciate that networks may have many more or different devices than shown inFIG. 6 . - In at least one of the various embodiments, one or more network monitoring computers (NMCs) may be arranged to monitor networks, such as, network 602. (See,
FIG. 4 ). In at least one of the various embodiments, NMCs may be arranged to generate one or more device relation models that represent the entities in a network. For example,device relation model 612 represents a device relation model corresponding to network 602. Accordingly,device relation model 612 includes nodes that represent the various entities that may be active in network 602. For example,entities 614, may represent some of the entities that are operative in network 602. In some embodiments, there may be more entities inmodel 612 than the number of actual computers and network devices present in network 602 since many network computers/devices may host more than one entity. For example, in some embodiments, a single network computer may host a web server and a database server. Accordingly, in this example, three entities may be included in the device relation model, one for the web server, one for the database server, and one for the network computer itself. - In this example,
device relation model 612 shows nodes that correspond to entities absent any edges. In some embodiments, initially some or all of the relationships between the entities may be unknown to the monitoring NMC, so some or all of the edges may be unknown and therefor omitted fromdevice relation model 612. Note, in at least one of the various embodiments, there may be pre-defined network architecture/topology information that may be available to the NMC. Accordingly, in some embodiments, the NMC may be able to determine some of the relationships between entities before observing network traffic. -
FIG. 7 illustrates a logical representation of a portion ofdevice relation model 700 in accordance with at least one of the various embodiments. In at least one of the various embodiments, device relation models may include nodes that represent entities and edges that represent relationships between the entities. In some embodiments, entities may represent servers, clients, switches, routers, NMCs, load balancers, applications, services, or the like. For example,entity 702 may be a server entity that has relationships with other servers, such as,entity 704 andentity 706. Likewise,entity 708 may be a server or other service that has a relationship withentity 704,entity 706, andentity 702. Further,entity 704 andentity 710 may have a relationship andclient entities 712 may have direct relationships withentity 710. - In at least one of the various embodiments, NMCs may be arranged to use
device relation model 700 to discover relationships between groups of entities. For example,device relation model 700 may be used to determine thatentity 702,entity client 712 may be in a related group because they are all on the same path through the graph. - In one or more of the various embodiments, one or more device relation models may be generated to represent different dimensions or concepts that may relate the one or more entities included in a model. For example, one device relation model may represent general dependencies among entities while another device relation model may be arranged to represent administration dependencies that show which entities may be arranged to administer other entities.
- Also, in one or more of the various embodiments, one or more device relation models may be arranged to represent various actions one or more anomaly analysts, or the like, may take while conducting an investigation of one or more anomalies. In some embodiments, one or more device relation models may be directed to different networks or sub-networks.
-
FIGS. 8A and 8B illustrate how a device relation model may evolve as the NMCs gather more information about the relationships between the entities in a network. -
FIG. 8A illustrates a logical representation ofdevice relation model 800 showing naïve relationships between the entities in accordance with the one or more embodiments. In at least one of the various embodiments, for example, a NMC may initially determine the entities in a network by observing the network traffic to obtain the source/destination network address fields in the network packets that flow through the network. In at least one of the various embodiments, each unique network address may represent a different entity in the network. - Likewise, in some embodiments, the NMC may be arranged to observe responses to broadcast messages, or the like. Additionally, in some embodiments, the NMC may be provided other configuration information (e.g., information provided by a configuration management database) that defines some or all of the entities in the network.
- In this example, for at least one of the various embodiments, the NMC has discovered/identified six entities in the network (
entity 802 through entity 812). Accordingly, in some embodiments, the NMC may be arranged to generate a device relation model, such as,device relation model 800 that represents the six discovered entities as nodes in the graph. Likewise, in some embodiments, edges indevice relation model 800 may represent the initial relationships as determined by the NMC. For example, in the initial stages of monitoring a network the NMC may be arranged to determine relationships based on which entities are observed to be communicating with each other. - However, in at least one of the various embodiments, NMCs may be arranged to provide a device relation model that represents the relationships between the entities that go beyond simple interconnectivity. Initially, in some embodiments, the NMC may define the initial relationships in the network based on which entities communicate with each other. However, in at least one of the various embodiments, as the NMC collects more information about the entities and their relationships to other entities, the NMC may modify
device relation model 800 to reflect the deeper understanding of these relationships. -
FIG. 8B illustrates a logical representation ofdevice relation model 800 showing informed relationships between the entities in accordance with the one or more embodiments. In at least one of the various embodiments, after sufficient monitoring has occurred, the NMC may have observed enough network traffic to evaluate and weight the relationships of the entities in the network. - In at least one of the various embodiments, some of the initial relationships may be determined to be incidental, spurious, or otherwise unimportant. Accordingly, the NMC may be arranged to remove (or de-prioritize) edges from
device relation model 800 that correspond to such relationships. For example, in at least one of the various embodiments, entities (e.g., Windows network domain controllers) in a network may be arranged to periodically exchange messages with one or more other entities for discovery/accountability purposes. Thus, in this example, some of the messaging observed by an NMC may be routine and otherwise not resulting from an interesting relationships between the sender and receiver. - In at least one of the various embodiments, NMC may be arranged to evaluate the communication between entities to attempt to determine the type of relationships and the importance of the relationships. Accordingly, in at least one of the various embodiments, NMCs may be arranged to collected metrics associated with the various network flows flowing the network to identify the flows that may be important. Likewise, in at least one of the various embodiments, NMC may be arranged discover and recognize the communication protocols used by entities in monitored networks. In some embodiments, the NMCs may be arranged to use the collected metrics and its understanding of the communication protocol to establish or prioritize relationships between the entities in the networks.
- In this example, for at least one of the various embodiments,
device relation model 800 has been modified to include relationships determined to be of importance. The nodes representing entities 802-812 are still present in but some of the edges that represent relationships in the network have been removed. For example, inFIG. 8A ,device relation model 800 includes an edge betweenentity 804 and entity 812. InFIG. 8B ,device relation model 800 omits the edge betweenentity 804 and entity 812. - In at least one of the various embodiments, the remaining edges in
device relation model 800 represent relationships between the entities that the NMC determined to be important for a given device relation model. Note, in at least one of the various embodiments, an NMC may employ a variety of metrics, conditions, heuristics, or the like, to identify relationships that may be of interest. For example, an NMC may be arranged to identify entities that represent certain applications on the network, such as, database servers, database clients, email servers, email clients, or the like, by identifying the communication protocols that may be used by the particular applications. In other cases, the NMC may determine an important relationship based on the number or rate of packets exchanged between one or more entities. Accordingly, the NMC may be configured to prioritize relationships between entities that exchange a high volume of traffic. - In at least one of the various embodiments, the NMC may analyze observed traffic to identify network packets that flow through particular paths in the device relation model. In some embodiments, NMCs may be arranged to trace or identify such paths connecting related entities by observing common data carried in the payloads or header fields of the network packets that are passed among entities in the network. For example, an NMC may be arranged to observe sequence numbers, session identifiers, HTTP cookies, query values, or the like, from all entities participating in transactions on the network. In some embodiments, the NMC may correlate observed network packets that may be requests and responses based on the contents of the network packets and known information about the operation of the underlying applications or protocols.
-
FIGS. 9A and 9B provide additional illustration of how a device relation model may evolve as the NMCs gather more information about the relationships between the entities in a network. -
FIG. 9A illustrates a logical representation ofdevice relation model 900 showing relationships between the entities based on observed network connections in accordance with the one or more embodiments. In at least one of the various embodiments, the NMC has provideddevice relation model 900 that represents the relationships betweenentity 902 throughentity 912. Heredevice relation model 900 shows relationships that may be associated with actual network links (e.g., physical links or virtual links) between the entities in the network. For example, the edges indevice relation model 900 may correspond to network flows that have been observed in the network. In some embodiments, an NMC may readily deduce these types of connection relationships by examining the source/destination fields in network packets observed in the network. Accordingly, in this example,entity 906 may have been observed exchanging data withentity 908 over the network. -
FIG. 9B illustrates a logical representation ofdevice relation model 900 showing phantom edges that represent relationships between the entities in accordance with the one or more embodiments. In some embodiments, networks may include entities that have important logical/operational relationships even though they do not exchange network packets directly with each other. Here, the NMC has discovered relationships betweenentity 902 andentity 908 even though they do not communicate directly with each other. Likewise, the NMC has discovered relationships betweenentity 904 andentity 912 even though they do not communicate directly with each other. Similarly,entity 908,entity 910,entity 912 have been found to be related even though there is no direct network link or direct communication between them. - In at least one of the various embodiments, the NMC may be arranged to represent such relationships using phantom edges. Phantom edges may represent relationships between entities that do not correspond to direct network links. For example,
entity 902 andentity 904 may be database clients andentity 908,entity 910, andentity 912 may be database servers. In this example,entity 902 andentity 904 access the database servers throughentity 906. In this example,entity 906 may be proxy-based load balancer of some kind. Accordingly, in this example there is no direct network link between the database clients and the database servers. Nor, as represented, do the database server entities (entity 908,entity 910, and entity 912) have direct connections to each other. - But, in some embodiments, the NMC may determine that the three database server entities (
entity 908,entity 910, and entity 912) are related because they are each receiving communications from the same load balancer (entity 906). Likewise, the NMC may determine a relationship between the database clients (entity 902 and entity 904) and the database servers (entity 908,entity 910, and entity 912) by observing the operation of the database transactions even though they do not communicate directly with each other. -
FIG. 10 illustrates a logical architecture ofnetwork 1000 that includes entities in accordance with the one or more embodiments. In at least one of the various embodiments, networks may include several (100s, 1000s, or more) computers or devices that may put network traffic on the network. As described above, (See,FIG. 4 andFIG. 5 ) network monitoring computers (NMCs) may be arranged to passively monitor the network traffic. In some embodiments, NMCs (not shown inFIG. 10 ) may have direct access to the wire traffic of the network enabling NMCs to access all of the network traffic in monitored networks. - In at least one of the various embodiments, the NMC may be arranged to identify entities in the network. Entities may include applications, services, programs, processes, network devices, or the like, operating in the monitored network. For example, individual entities may include, web clients, web servers, database clients, database servers, mobile app clients, payment processors, groupware clients, groupware services, or the like. In some cases, multiple entities may co-exist on the same network computer, or cloud compute instance.
- In this example,
client computer 1002 may be hostingweb client 1004 andDNS client 1006. Further,server computer 1008 may be hostingweb server 1010,database client 1014, and DNS client 1021. Also, in this example:server computer 1016 may be arranged tohost database server 1018 andauthorization client 1020;server computer 1022 may be arranged to hostauthorization server 1024; andserver computer 1026 may be arranged toDNS server 1028. - In at least one of the various embodiments, some or all of the applications on a computer may correspond to entities. Generally, applications, services, or the like, that communicate using the network may be identified as entities by an NMC. Accordingly, there may be more than one entity per computer. Some server computers may host many entities. Also, some server computers may be virtualized machine instances executing in a virtualized environment, such as, a cloud-based computing environment. Likewise, one or more servers may running in containerized compute instances, or the like.
- In at least one of the various embodiments, an individual process or program running on a network computer may perform more than one type of operation on the network. Accordingly, some processes or programs may be represented as more than one entity. For example, a web server application may have an embedded database client. Thus, in some embodiments, an individual web server application may contribute two or more entities to the device relation model.
- In at least one of the various embodiments, the NMC may be arranged to monitor the network traffic to identify the entities and to determine their roles. In at least one of the various embodiments, the NMC may monitor the communication protocols, payloads, ports, source/destination addresses, or the like, or combination thereof, to identify entities.
- In at least one of the various embodiments, the NMC may be preloaded with configuration information that it may use to identify entities and the services/roles they may be performing in the network. For example, if an NMC observes a HTTP GET request coming from a computer, it may determine there is a web client entity running on the host. Likewise, if the NMC observes a
HTTP 200 OK response originating from a computer it may determine that there is a web server entity in the network. - In at least one of the various embodiments, the NMC may use some or all of the tuple information included in network traffic to distinguish between different entities in the network. Further, the NMC may be arranged to track the connections and network flows established between separate entities by correlating the tuple information of the requests and responses between the entities.

FIG. 11 illustrates a logical representation of a data structure fordevice relation model 1100 that includes entities in accordance with the one or more embodiments. In at least one of the various embodiments, network monitoring computers (NMCs) may be arranged generate device relation models, such as,device relation model 1100. In this example,device relation model 1100 represents the entities discoverednetwork 1000 shown inFIG. 10 . - In at least one of the various embodiments, as described above, NMCs may arrange device relation models to represent the relationship the entities have to each other rather than just modeling the network topology. For example,
entity 1106,entity 1110, andentity 1118 are each related to the DNS system innetwork 1000. Therefore, in this example, for some embodiments, the NMC may arrangedevice relation model 1100 such that all of the DNS related entities (entity 1106,entity 1110, and entity 1118) are neighbors in the graph. Accordingly, in some embodiments, even thoughentity 1106 corresponds toDNS client 1006 onclient computer 1002, the NMC maygroup entity 1106 with the other DNS entities rather than put it next other entities in the same computer. - In at least one of the various embodiments, the NMC may be arranged to generate
device relation model 1100 based on the relationships that the entities have with each other. Accordingly, in some embodiments, the edges in the graph may be selected or prioritized (e.g., weighted) based on the type or strength of the relationship. In at least one of the various embodiments, the metrics used for prioritizing the edges in a device relation model may be selected/computed based on configuration information that includes rules, conditions, pattern matching, scripts, computer readable instructions, or the like. In some embodiments, NMCs may be arranged to apply this configuration information to the observed network packets (e.g., headers, payloads, or the like) to identify and evaluate relationships. - In at least one of the various embodiments, in
device relation model 1100, theedge connecting entity 1104 andentity 1108 is depicted thicker to represent the close relationship the web server entity has with the database client entity. This reflects that the web server may be hosting a data centric web application that fetches data from a database when it receives HTTP requests from clients. Likewise, fordevice relation model 1100 the relationship between the database client (entity 1108) and the database server (entity 1112) is also a strong relationship. Similarly, the relationship between the authorization client (entity 1114) and the authorization server (entity 1116) is a strong relationship. - Also, in this example, the client (entity 1102) and DNS client 1 (entity 1106) have a strong relationship and it follows that DNS client 1 (entity 1106) has a strong relationship with the DNS server (entity 1118). However, DNS client 2 (entity 1110) has a weak relationship with the DNS server (entity 1118). In this example, this may make sense because DNS client 1 (entity 1106) is often used by the client (entity 1102) to send lookup requests to the DNS server. In contrast, in this example, DNS client 2 (entity 1110) is rarely used since it is running on the server computer (
server computer 1008 inFIG. 10 ) and it may rarely issue name lookup requests. - In at least one of the various embodiments, the NMC may traverse
device relation model 1100 to identify entities that may be closely related together and associate them into a group. For example, in some embodiments, indevice relation model 1100,entity 1104,entity 1108, andentity 1112 may be grouped since they each have strong relationships with each other. - Accordingly, in at least one of the various embodiments, the NMC may be arranged to correlate error signals that may be associated with one or more entities that are in the same group to determine that an anomaly may be occurring. Related error signals that may propagate through a group of closely related entities may be recognized as a bigger problem that rises to an actual anomaly.
- In at least one of the various embodiments, the NMC may be arranged to have configuration information, including, templates, patterns, protocol information, or the like, for identifying error signals in a group that may have correlations that indicate they indicate an anomaly.
- In some embodiments, the NMC may be arranged to capture/monitor incoming and outgoing network traffic for entities in a monitored network. Also, the NMC may be arranged to employ various protocol analysis facilities, such as, state machines, mathematical models, or the like, to track expected/normal operations of different types of entities in a monitored network. Accordingly, in at least one of the various embodiments, the NMC may monitor the state of operations for entities that are working together. For example, a web client entity, such as,
entity 1102, may make an HTTP request toweb server entity 1104, that in turn triggers theweb server entity 1104 to issue a database request toDB client entity 1108 that in turn is provideddatabase server entity 1112. In some embodiments, the NMC may monitor the operation of each entity in the group by observing the network traffic exchanged between the entities in a group. Thus, in some embodiments, if an error atdatabase server entity 1112 causesweb client entity 1102 to drop its connection because of a timeout (or the user cancel the request, or repeats the same request before the response is sent), the NMC may be able to correlate the error atdatabase server entity 1112 with the “timeout” error atweb client entity 1102 to recognize what may be a serious anomaly. -
FIG. 12 represents a logical representation ofsystem 1200 for transforming monitored network traffic into anomaly profile objects (e.g., anomaly profiles) or investigation profile objects (e.g., investigation profiles) in accordance with one or more of the various embodiments. In one or more of the various embodiments,NMC 1202 may be arranged to monitornetwork traffic 1204.

In one or more of the various embodiments, anomaly profiles may include collections of one or more fields with values that may be based onnetwork traffic 1204 or metrics associated withnetwork traffic 1202. In one or more of the various embodiments, one or more of the metrics included in an anomaly profile may correspond to metrics collected by the NMC. In other embodiments, one or more of the metrics included in an anomaly profile may be composed of two or more metrics. Also, in one or more of the various embodiments, one or more metrics or features of an anomaly profile may be computed based on one or more observed metrics. - Further, in one or more of the various embodiments, metric values included in anomaly profiles may be normalized or fit to a common schema as well as arithmetically normalized. Normalizing metric values to a common schema may include bucketing values. For example, in some embodiments, observed metrics that have continuous values may be mapped to named buckets, such as high, medium, low, or the like.
- In one or more of the various embodiments, NMCs may be arranged to execute one or more ingestion rules to perform pre-processing, such as, the data normalization, that may be required to map observed (raw) metrics into anomaly profile values or features. In one or more of the various embodiments, one or more ingestion rules may be built-in to NMCs while other ingestion rules may be provided via configuration information, plug-ins, rule based policies, user input, or the like.
- In one or more of the various embodiments, one or more anomaly profiles may be associated with computer readable instructions that enforce one or more matching rules or filter rules. Accordingly, in one or more of the various embodiments, inference engines may be arranged to execute the one or more matching rules or filters to determine if monitored network activity should be associated with an anomaly profile. In some embodiments, one or more matching rules may be comprised of pattern matching instructions, such as, regular expressions, or the like. In some embodiments, one or more matching rules may be comprised one or more compound or cascading rules or sub-rules for matching network activity to anomaly profiles. In some embodiments, the same network activity may match two or more anomaly profiles.
- In one or more of the various embodiments, anomaly profiles may include one or more features that may include threshold values. For example, a traffic flood anomaly profile may include a feature or condition that is met by one or more metrics, such as, the number of connection attempts per minute or second, exceeding a threshold value. Likewise, in some embodiments, anomaly profiles may be associated other features, such as, the occurrence of one or more known error responses, latency or other wait times exceeding a timeout value, unexpected attempts to access protected/critical entities, users performing unexpected or abnormal activity, or the like. Generally, in one or more of the various embodiments, the one or more features that define an anomaly profile may be comprised of one or more metric values, one or more network traffic patterns, or other monitored signals.
- In some embodiments, anomaly profiles may be tagged or labeled by the NMCs, users, investigators, or the like. In one or more of the various embodiments, NMCs may be arranged to automatically tag or label anomaly profiles with generated labels or tags based on underlying network traffic associated with the anomaly profile. Likewise, in some embodiments, users, analysts, or investigators may be enabled to add or modify anomaly profile labels or tags to improve reporting, visualizations, human readability, or the like.
- In one or more of the various embodiments, anomaly profiles may be employed by inference engines, analysis engines, anomaly engines, or the like, for detecting the occurrence one or more anomalies in a monitored network. Accordingly, in one or more of the various embodiments, metrics related to the occurrence of network traffic associated with anomaly profiles may be collected or tracked. For example, the number of times network traffic associated with a particular anomaly profile may be recorded as metric.
- Similarly, in one or more of the various embodiments, investigation profiles may be determined based on monitoring the network traffic associated with the activity that analysts or investigators perform in response to the occurrence of anomaly. In some embodiments, investigation profiles may be arranged to represent the some or all of the sequence of steps or actions an investigator takes during an investigation.
- In some embodiments, during the course of an investigation, an investigator may perform actions associated with two or more investigation profiles. For example, a first investigation profile may include navigating to a web page that displays an error report and a second investigation profile may include the network activity that may be associated with the investigator remote logging into a server computer and view log files in a command console.
- In one or more of the various embodiments, an investigation profile may include one or more investigation profiles such that the investigation profile may be considered a compound investigation profile that is comprised of two or more investigation profiles. For example, referring to previous example, a compound investigation profile may include the first investigation profile and the second investigation profile examples described above.
- In one or more of the various embodiments, NMCs may be arranged to track investigator activity related to the investigator action in the investigation workspace (e.g., applications for managing or investigating incidents or anomalies), such as, user-interface interactions, viewing reports or visualizations, annotations or comments added by the investigator, or the like. These local activities may be associated with the network activity associated with the investigator actions. Accordingly, in one or more of the various embodiments, the investigation profiles may include a record of local actions and network activity associated with an investigation.
- Similar to anomaly profiles, in some embodiments, investigation profiles may be comprised of one or more features that may be associated with one or more metrics or one or more portions of network traffic as described above for anomaly profiles.

decision block 1708, in one or more of the various embodiments, if there are one or more associated investigation profiles, control may flow to block 1710; otherwise, control may flow to block 1712. In some embodiments, some anomalies or anomaly profiles may be unassociated with any investigation profiles. For example, if a never before detected anomaly occurs, it may not be associated with an investigation profile. - At
block 1710, in one or more of the various embodiments, the one or more NMCs may be arranged to provide the one or more investigation profiles to one or more investigators. As described above, investigation information that includes one or more investigation profiles may be provided to an investigator. - At
block 1712, in one or more of the various embodiments, the one or more NMCs may be arranged to collect one or more metrics based on monitored investigation activity. As the investigator performs one or more actions to investigate the anomaly, the NMCs may collect information about the investigation activity and associated with the anomaly profile or investigation profiles (if any). In some embodiments, if there are no associated investigation profiles, the investigation activity may be used to generate a new investigation profile that may be associated with anomaly profile. Accordingly, if the same anomaly is detected in the future, the investigation profile may be provided to the investigator to guide the investigation of the anomaly or other anomalies that are associated with the same anomaly profile. Next, control may be returned to a calling process. -

After a start block, atblock 1802, in one or more of the various embodiments, one or more NMCs may be arranged to collect one or more metrics or other information based on monitoring the network traffic in the monitored networks. As described above, NMCs may be arranged to monitor the network traffic associated with various entities in the monitored networks. - At
decision block 1804, in one or more of the various embodiments, if the one or more NMCs determines the one or more portions of the network traffic matches or is associated with one or more anomaly profiles, control may flowblock 1806; otherwise, control may loop back toblock 1902. - At
block 1806, in one or more of the various embodiments, the one or more NMCs may be arranged to provide one or more investigation playbooks to one or more investigators. In one or more of the various embodiments, organizations may provide of define investigation playbooks that define specific investigation activity that an investigator should perform during the investigation of some or all anomalies. In some embodiments, some anomalies may have specific investigation playbooks. In other cases, one or more general investigation playbooks may be provided. - In one or more of the various embodiments, investigation playbooks may include one or more checklists, workflows, instructions, or the like, that an investigator may be expected to follow to investigate an anomaly or class of anomalies. In some embodiments, investigation playbooks may be associated with one or more anomaly profiles. Accordingly, in one or more of the various embodiments, if the detected anomaly is associated with an anomaly profile that is associated with an investigation playbook, the NMCs may provide it to the investigator. In some embodiments, the investigator may already have access to one or more investigation playbooks. Accordingly, in some embodiments, the investigator (or the investigation workspace) may provide the investigation playbook rather than the NMC.
- At
block 1808, in one or more of the various embodiments, the one or more NMCs may be arranged to provide one or more investigation profiles to the one or more investigators. As described above, one or more investigation profiles may be associated with the anomaly profile that may be associated with anomaly. Accordingly, if there are relevant (matching) investigation profiles available, the NMC may provide them to the investigator. - At
block 1810, in one or more of the various embodiments, the one or more NMCs may be arranged to monitor the network traffic that may be associated with the investigation activity performed by the one or more investigators. In one or more of the various embodiments, investigators may take various actions to investigate the anomalies. In some embodiments, the investigation profiles or investigation playbooks may provide instructions, checklists, workflows, or the like, that an investigator may use to guide them in the investigation of the anomaly. However, in one or more of the various embodiments, investigators may be enabled to perform investigation activities outside of the activities defined in the investigation profiles or investigation playbooks. - Accordingly, as described above, the NMCs may monitor the investigation activity performed by the investigator, including the activities prescribed by investigation profiles or investigation playbooks and activity not included in investigation profiles or investigation playbooks.
- At
block 1812, in one or more of the various embodiments, the one or more NMCs may be arranged to compare the investigation activity to the one or more investigation playbooks. In one or more of the various embodiments, NMCs may be arranged to evaluate if the investigator followed the guidance of the investigation profiles or the investigation playbook. For example, if the investigation profile prescribed four actions in a particular order, the NMCs may track if the investigator performed the four actions in the prescribed order. Likewise, if the investigator was using an investigation playbook, the NMCs may track if the investigator performed the actions included in the playbook. - In some embodiments, the actual investigation activity performed by the investigator may be compared to the activity the investigator may report having performed. For example, if the investigator reports that a database backup was performed before debugging the database as part of the investigation of the anomaly, the investigation activity monitored by the NMCs may confirm that the database backup was actually performed.
- At
block 1814, in one or more of the various embodiments, the one or more NMCs may be arranged to provide one or more compliance or deviation reports based on the comparison of the investigation activity to the investigation playbooks. In one or more of the various embodiments, reports that contain information related to how closely the investigator followed the investigation playbooks or how the investigator followed the investigation profiles may be determined based on the monitor investigation activity. As described above, the NMCs may be monitor the network traffic or network activity associated with each investigation activity. Accordingly, additions or omissions may be noted in a report. For example, if prescribed investigation profile or investigation playbook included ten ordered actions, the NMCs may grade or score the investigation based on how many of the ten actions were performed, the time it took to complete the investigation, how many of other additional actions were performed, or the like. - In some embodiments, the report information may indicate that the investigator is not performing some or all of the actions recommended or prescribed by investigation playbooks or investigation profiles. Likewise, the reports may indicate that an investigation playbook is incorrect or inadequate for the anomaly that was being investigated. Accordingly, in some embodiments, organizations may determine if their current investigation playbooks are sufficient or whether they need to be updating. For example, in some embodiments, a low scoring investigation may represent a poorly designed investigation playbook rather than a poorly performing investigator.
- Likewise, in some embodiments, if investigators deviate from investigation profiles this may indicate that the investigation profiles may incorrect for the particular anomaly that was investigated. In this case, it may indicate that the investigation profile should be re-trained, re-optimized, discarded, or the like. Alternatively, in some embodiments, if an investigation model was employed to select the investigation profile, the deviation may be used to evaluate whether the investigation model is selecting relevant investigation profiles or whether the investigation model requires re-training. Next, control may be returned to a calling process.

FIG. 19 illustrates a flowchart ofprocess 1900 for training or optimizing improved investigation profiles based on historical anomaly profile activity, historical investigation profile activity, and historical network activity in accordance with one or more of the various embodiments. In some embodiments, because some investigation profiles may be generated based on actual network activity performed by investigators they may include redundant actions, risky actions, unnecessary actions, or the like, that may be introduced by investigators that are unfamiliar with some types of anomalies. For example, the first time an anomaly is encountered, investigators may perform one or more exploratory actions that may ultimately be unnecessary to successfully the anomaly. Thus, in some cases, for some embodiments, one or more investigation profiles, especially new investigation profiles, may include actions that could be removed, re-ordered, combined, or the like. Accordingly, in one or more of the various embodiments, inference engines may be arranged to perform one or more actions to attempt to optimize investigation profiles. - After a start block, at
block 1902, in one or more of the various embodiments, the one or more NMCs may be arranged to provide anomaly profile history. In one or more of the various embodiments, NMCs may be arranged to track the amount of times that network activity associated with a given anomaly profile has been observed in the one or more monitored networks. In some embodiments, this information may include a data sketch of the network activity that was associated with each anomaly profile. In some embodiments, this may include one or more metrics, such as, time of occurrence, entities in the network associated with the occurrence, duration of the activity, statistical values associated with various metrics (e.g., mean, median, distributions or the like), or the like. - In one or more of the various embodiments, NMCs may be provided (or may capture) network traffic associated with the one or more anomaly profiles. In some embodiments, the captured network traffic may be stored or indexed in other traffic/packet capture data stores. Accordingly, in one or more of the various embodiments, the NMCs may request captured network traffic associated with the one or more anomaly profile. For example, in one or more of the various embodiments, an anomaly profile may be associated with one or more incoming/outgoing network messages, applications, services, ports, protocols, packet header values, packet payload values, or the like, or combination thereof. Accordingly, in this example, NMCs may provide a request (e.g., provide a query) that includes one or more parameter values to select captured network traffic or other historical metrics that may be associated with one or more anomaly profiles.
- At
block 1904, in one or more of the various embodiments, the one or more NMCs may be arranged to provide investigation profile history. In one or more of the various embodiments, NMCs may be arranged to track the amount of times that network activity associated with a given investigation profile has been observed in the one or more monitored networks. In some embodiments, this information may include a data sketch of the network activity that was associated with each investigation profile. In some embodiments, this may include one or more metrics, such as, time of occurrence, entities in the network associated with the occurrence, duration of the activity, statistical values associated with various metrics (e.g., mean, median, distributions or the like), or the like. - In one or more of the various embodiments, NMCs may be provided (or may capture) captured network traffic associated with the one or more investigation profiles. In some embodiments, the captured network traffic may be stored or indexed in other traffic/packet capture data stores. Accordingly, in one or more of the various embodiments, the NMCs may request captured network traffic associated with the one or more investigation profiles. For example, in one or more of the various embodiments, an investigation profile may be associated with one or more incoming/outgoing network messages, applications, services, ports, protocols, packet header values, packet payload values, or the like, or combination thereof. Accordingly, in this example, NMCs may provide a request (e.g., provide a query) that includes one or more parameter values to select captured network traffic or other historical metrics that may be associated with one or more investigation profiles.
- At
block 1906, in one or more of the various embodiments, the one or more NMCs may be arranged to evaluate one or more investigation profiles. In one or more of the various embodiments, an inference engine, such as,inference engine 324, or the like, may be arranged to evaluate the one or more investigation profiles based on one or more features of the provided anomaly profiles, investigation profiles, the anomaly profile history, or the investigation profile history. - In one or more of the various embodiments, the historical information collected above may include network activity information, including metrics collected by the NMCs, that show which investigation profiles were used to investigate various anomalies associated with the anomaly profiles.
- Accordingly, in one or more of the various embodiments, investigation profiles may be evaluated based on the investigation success rates, average time to complete investigations, number of actions or steps per investigation, or the like.
- Also, in one or more of the various embodiments, investigation profiles may be evaluated based on risk factors or performance impacts associated with prescribed investigation actions. In some embodiments, each risk factor or class of risk factors may be associated with a risk score. Likewise, in some embodiments, one or more actions may be associated with performance impact scores. Accordingly, in one or more of the various embodiments, investigation profiles may be associated with an aggregate risk score or aggregate performance score based on the score of the actions prescribed by a given investigation profile.
- For example, in some embodiments, risky actions may include, accessing critical entities, using commands that require super-user roles, starting/stopping critical processes, unsecure/unmonitored access of sensitive data, moving or sharing sensitive information, decrypting normally encrypted data, changing users, enabling remote access to sensitive entities, or the like.
- Also, for example, in some embodiments, performance impacting actions may include actions that degrade host or network performance, such as, bulk copying, database dumps, backups, restoring from backups, brute force text searches, ad-hoc queries into production databases, queries or searches of unstructured data stores, accessing remote entities or systems having limited bandwidth or computing power, or the like.
- In one or more of the various embodiments, NMCs may assign risk or performance impact scores to various actions based on configuration information. Accordingly, organizations may be enabled to adjust risk scores or performance impact scores to various actions based on their operational requirements.
- At
block 1908, in one or more of the various embodiments, the one or more NMCs may be arranged to optimize one or more investigation profiles. In one or more of the various embodiments, inference engines may be arranged to determine one or more optimizations to improve existing investigation profiles. In some embodiments, inference engines may identify one or more redundant actions that may be eliminated. Also, in some embodiments, an investigation profile may include two or more different actions that produce the same result. For example, an investigation profile may prescribe that an investigator log into computer A to review resource A and then log into computer B to review B even though resource A and resource B may be reviewed directly from the investigators workstation. Accordingly, in this example, an inference engine may detect the unnecessary remote access to computers A and B and recommend that the steps of logging into computer A and computer B be removed from the investigation profile. - Likewise, for example, inference engines may be arranged to re-order one or more actions to reduce the number actions required for an investigation. For example, an investigation profile may prescribe that the investigator log into computer A to review resource A and then logout and perform some intervening steps before logging back into computer A to review resource B. In this example, the inference engine may identify that one logon to computer A may be eliminated if resource A and resource B are reviewed the first time the investigator logs in to computer A.
- In some embodiments, inference engines may evaluate one or more investigation profiles to identify one or more activities (e.g., investigator actions, steps, or the like) that may be factored out to simplify or otherwise reduce the complexity of one or more investigation profiles identified, such as, discovering functionally equivalent investigation profiles that are more efficient.
- In one or more of the various embodiments, the one or more NMCs may be arranged to employ one or more heuristics it identify one or more circumstances that may be suitable for optimizations. In some embodiments, these heuristics may be defined using computer readable instructions that may be built-in, provided by configuration information, provided by plugins, or the like.
- Also, in one or more of the various embodiments, NMCs may employ machine learning to learn one or more investigation profiles that may perform better for some anomaly profiles than the investigation profiles typically or previously used by investigators. In some embodiments, machine learning may identify that investigators may be using sub-optimal investigation profiles to investigate a given set of anomalies. In some cases, this may be because investigators are following an investigation playbook that is sub-optimal. Or, in some cases, investigators may be choosing the investigation profiles out of habit and not recognizing subtle differences in anomalies that degrade the performance or efficacy of the investigation profiles they are following.
- Accordingly, in one or more of the various embodiments, inference engines may be provided various anomaly profile features as inputs to learn the optimized set of investigation profile features that are likely to produce successful investigations. In some embodiments, this may leverage circumstances where there may be several investigation profiles that are associated with the same anomaly profiles. In such cases, the inference engine may employ machine learning to learn which features from the several investigation profile features may be optimal for investigating a given anomaly. In some cases, inference engine may generate investigation profiles based on learning from the investigation profiles that were generated by monitoring investigation activity performance by investigators.
- Also, in one or more of the various embodiments, inference engines may be arranged to employ machine learning to identify groupings of anomalies, anomaly features, investigation profile features, investigation profile actions, or the like, that may be non-obvious. Accordingly, in one or more of the various embodiments, machine learning may discover that several anomalies may have commonalities that may be investigated using the same steps or actions.

In one or more of the various embodiments, investigation profile performance may be monitored in real-time based on network activity in the monitored networks. - In one or more of the various embodiments, investigation profiles may be evaluated based on their success or failure of the investigation of anomalies. In some embodiments, investigation models may be associated with a score that represents the quality of investigation profile recommendations. Accordingly, in some embodiments, poor evaluations may result in this performance score being decreased. Likewise, in some embodiments, good evaluations may result in this performance score being increased. Thus, in some embodiments, if the performance score of an investigation profile falls below a threshold value, the investigation model may be recommended for re-training or deactivation.
- In some embodiments, the NMCs may be arranged to tag or flag the one or more investigation profiles that produce poor results. In some embodiments, investigation profiles that have performance scores less than a defined threshold value may be automatically deactivated.
- At
block 1914, in one or more of the various embodiments, optionally, the one or more NMCs may be arranged to determine one or more investigation profiles for re-optimization. In one or more of the various embodiments, NMCs may be arranged to periodically re-optimize some or all investigation profiles. In some embodiments, all investigation profiles may be automatically selected for re-optimization based on performance scores. - In one or more of the various embodiments, the period for re-optimization investigation profiles may be impacted by other factors, such as, the network activity, anomaly profiles, entities, services, applications, sources, destinations, users, or the like, that may be associated with an investigation profile. For example, one or more investigation profiles associated with mission critical entities may be configured to be re-trained more often than investigation profiles associated with less important entities. As these determinations may be dependent on the operational considerations of the monitored networks, NMCs may be arranged to employ configuration information provided by configuration files, file system policies, built-in defaults, user input, or the like, combination thereof, to determine re-training frequency or re-training sensitivity. Next, control may be returned to a calling process.

- Also, in one or more of the various embodiments, NMCs may employ machine learning to discover one or more investigation profiles that may perform better for some anomaly profiles than the investigation profiles typically or previously used by investigators. In some embodiments, machine learning may identify that investigators may be using sub-optimal investigation profiles to investigate a given set of anomalies. In some cases, this may be because investigators are following an investigation playbook that is sub-optimal. Or, in some cases, investigators may be choosing the investigation profiles out of habit and not recognizing subtle differences in anomalies that degrade the performance of the investigation profiles they are using.
- In one or more of the various embodiments, classifiers trained by machine learning may identify investigation profiles that have fewer steps or a highly likelihood of success than the investigation profiles commonly used to investigate a given anomaly.
- At
block 2008, in one or more of the various embodiments, the one or more NMCs may be arranged to obtain feedback associated with the one or more candidate investigation models. In one or more of the various embodiments, NMCs may be arranged to provide interactive reports that enable users or investigators to review the investigation models. Accordingly, in one or more of the various embodiments, users or investigators may be enabled score or rate one or more investigation models. - In one or more of the various embodiments, as described above, investigators may be enabled to submit an investigation status or result when an investigation is closed. In some embodiments, the one or more NMCs may be arranged to enable investigators provide additional feedback, such as, grades, ranks, or the like, that may be used to evaluate the investigation profiles that were recommended by an investigation model. Accordingly, in one or more of the various embodiments, if an investigation model is recommending investigation profiles that receive poor grades from investigators, the investigation model may be evaluated poorly.
- At
block 2010, in one or more of the various embodiments, the one or more NMCs may be arranged to deploy the one or more investigation models for use by investigators to investigate anomalies that may occur in the monitored networks. In one or more of the various embodiments, one or more investigation models may be deployed or activated for monitoring network traffic in the one or more monitored networks.

block 2012, in one or more of the various embodiments, one or more NMCs may be arranged to evaluate the performance of the one or more investigation models. In one or more of the various embodiments, investigation model performance may be monitored in real-time based on network activity in the monitored networks. - In one or more of the various embodiments, investigation models may be evaluated based on the success or failure of the investigations based on investigation profiles that may be recommended by the investigation models. For example, in some embodiments, in response to the occurrence of an anomaly, an investigation model may select one or more investigation profiles to provide to an investigator. If the investigator follows the investigation profile and the investigation is unsuccessful, the investigation model may receive a poor evaluation. In some embodiments, investigation models may be associated with a score that represents the quality of investigation profile recommendations. Accordingly, in some embodiments, poor evaluations may result in this performance score being decreased. Likewise, in some embodiments, good evaluations may result in this performance score being increased. Thus, in some embodiments, if the performance score falls below a threshold value, the investigation model may be recommended for re-training.
- In some embodiments, the NMCs may be arranged to tag or flag the one or more investigation models that receive poor evaluations. In some embodiments, investigation models that receive an evaluation score that is less than a defined threshold value may be automatically deactivated. In some embodiments, this may be considered a temporary adjustment that may remain in effect until the investigation model is re-trained or the evaluation of the investigation model changes.
- In one or more of the various embodiments, the one or more NMCs may be arranged to evaluate the performance of investigators based on if they follow the recommended investigation profiles. For example, in some embodiments, investigators that fail to follow recommended investigation profiles and unsuccessfully investigate an anomaly may receive poor evaluations. Also, for example, investigators that perform additional investigative actions or activity that resolve the investigation when the actions associated with the recommended investigation profiles fail, may receive good evaluations.
- At
block 2014, in one or more of the various embodiments, optionally, the one or more NMCs may be arranged to determine one or more investigation models for re-training. In one or more of the various embodiments, NMCs may be arranged to periodically re-train some or all investigation models.

In other embodiments, one or more investigation models may be selected for re-training based on evaluation scores associated with the investigation models. - In one or more of the various embodiments, the period for re-training investigation models may be impacted by other factors, including investigation model priority, investigation model category, or the like. Accordingly, in one or more of the various embodiments, selecting an investigation model for re-training may depend on various characteristics of the network activity, anomaly profiles, investigation profiles, or the like, that may be associated with the investigation model, such as, entities, services, applications, sources, destinations, users, or the like, or combination thereof. For example, one or more investigation models associated with mission critical entities may be configured to be re-trained more often than one or more investigation models that may be associated with less important entities. As these determinations may be dependent on the operational considerations of the monitored networks, NMCs may be arranged to employ configuration information provided by configuration files, file system policies, built-in defaults, user input, or the like, combination thereof, to determine re-training frequency or re-training sensitivity.
