With respect to the interpretation of a term, it is to be interpreted in accordance with the broadest reasonable meaning of the art to which that term is entitled.
A cloud virtual gateway is a service of network forwarding capability on one cloud. And providing corresponding data processing capacity in the cloud network service on the cloud. Different application scenarios may correspond to different cloud virtual gateways. The cloud virtual gateway instance used by the user side would correspond to a cloud virtual gateway server. This document refers primarily to the location of fault scenarios, and refers collectively to such network forwarding services on the cloud as cloud virtual gateways.
A Cloud Virtual gateway product provides a set of isolated on-Cloud network space for a user using a Cloud in a Cloud Virtual network (Virtual Personal Cloud), and the user can build an own on-Cloud network environment through various Cloud Virtual gateway products such as an NAT gateway, a VPN gateway and a private line gateway according to own requirements. When cloud virtual gateway products such as NAT gateways, VPN gateways, private line gateways, and the like fail, there is a risk that the service of a user on the cloud is affected due to the failure of the cloud virtual gateway itself. It is desirable to be able to locate the cause of the fault quickly after the fault has occurred.
The embodiment of the invention provides a fault positioning method applied to a cloud virtual gateway system. The cloud virtual gateway system can comprise a cloud server, a host machine of the cloud server, a first network device, a virtual gateway server, a second network device and a destination server, wherein network data flow in the devices in sequence. As shown in fig. 1, data of the cloud server 101 flows to a host 102 of the cloud server, data of the host 102 flows to a first network device 103 (for example, a switch, a router, a firewall, or the like), data of the first network device 103 flows to a virtual gateway server 104, data of the virtual network server 104 flows to a second network device 105 (for example, a switch, a router, a firewall, or the like), and reaches a destination server 106 via the second network device 105.
Referring to fig. 2, fig. 2 is a flowchart illustrating a method for locating a fault with a virtual gateway according to an embodiment of the present invention, where the method for locating a fault with a virtual gateway is applied to the virtual gateway system shown in fig. 1. The method for positioning the fault of the virtual gateway provided by the embodiment of the invention can comprise the following steps: step S201, step S202, and step S203. It should be noted that the embodiment of the present invention is not limited to the above three steps, and other additional steps may be included in other embodiments of the present invention.
Step S201, monitoring an operating state of the cloud virtual gateway system.
In an embodiment of the present invention, as shown in fig. 3, the monitoring of the operation state of the cloud virtual gateway system may include: monitoring various states of the cloud virtual gateway, including information such as CPU occupancy rate, memory occupancy rate, I/O, disk, network card flow, network card packet access amount, network card packet access error and the like of a gateway physical server. For example, the cloud virtual gateway server may monitor CPU occupancy, memory occupancy, I/O, disk, network card traffic, network card packet access amount, network card packet access error, etc. through a plurality of agents, and each agent monitors one parameter. These monitoring may be performed centrally on an integrated monitoring platform. In addition, a threshold value can be set, and when the threshold value is exceeded, alarm information is sent out, for example, the alarm can be sent out by means of providing a short message and the like.
By monitoring the cloud virtual gateway, the purpose of monitoring the state of a physical server of a cloud virtual gateway product in real time can be achieved. When fault automatic positioning is carried out, monitoring information can be automatically checked in real time, or information required on a related virtual gateway physical server can be automatically called when needed.
Step S202, when a fault is monitored, generating a network topology of a plurality of predetermined node devices in the cloud virtual gateway system according to scene information associated with the fault, wherein the plurality of predetermined node devices comprise: cloud server host computer, cloud virtual gateway server, network equipment.
When a fault occurs, the network topology of the cloud virtual gateway system can be generated according to scene information and the like associated with the fault. Common fault scenarios include forwarding abnormal faults such as a large number of packet retransmissions, timewait accumulation, packet errors and the like on the cloud virtual gateway. Taking the private line gateway as an example, the user uses the private line gateway, and the sudden service is blocked. According to the information of the user, the data flow of the user service in the cloud virtual gateway system can be analyzed according to the flow direction shown in fig. 1 (cloud server- > host- > private line gateway- > private line access switch), so as to form a network topology. In the fault of the private line gateway, the scene information related to the fault may be information of the user and an instance of the cloud virtual gateway service used by the user. In other fault scenarios, the fault-associated scenario information may be user information or other information associated with the fault.
The generation of the network topology and the subsequent detection mode selection of the embodiment of the invention can take scene information related to the fault as input to automatically position the fault.
The network topology of the application of the cloud virtual gateway product service operated by the user on the cloud can be generated in a one-key mode, and particularly, the network topology is generated by carrying out special identification on key nodes such as the related cloud virtual gateway product. The key nodes may include: the cloud server hosts, the cloud virtual gateway servers, the network devices (such as switches and the like) and the like are marked in the network topology of the cloud virtual gateway system, so that the fault location is convenient.
In some specific embodiments, generating a network topology of a plurality of predetermined node devices in the cloud virtual gateway system includes: and acquiring the IP address of a host machine corresponding to the cloud server, the IP address of a cloud virtual gateway server flowing through the network and the IP address of network equipment to form the network topology of the cloud virtual gateway system. In some other embodiments, in addition to generating the network topology for the nodes such as the cloud server host, the cloud virtual gateway server, and the network device, the network topology may be generated by other node devices of the cloud virtual gateway system according to the requirement of the fault scenario.
Step S203, according to the network topology and the operation state, using one or more selected detection modes to locate the cause and the position of the fault, wherein the detection modes include: network flow logs, packet capture tools, and health checks.
In the embodiment of the present invention, the cause of the fault occurrence may be located by using one or more selected detection manners according to the network topology generated in step S202 and the operation state monitored in step S201, that is, the cause of the fault may be detected by using any one of three detection manners. If the cause of the fault cannot be accurately determined by using one detection mode, the fault can be detected by using two or three detection modes. As shown in fig. 3, the three detection modes can be implemented by the operation and maintenance tool integration platform.
The above detection method will be described in detail below.
First, a network flow log detection method is introduced.
In some embodiments, the network flow log start of a specific failure point may be adopted, and specifically, the network flow log detection manner may include: setting a log opening threshold value of a preset fault of the cloud virtual gateway system, determining whether an operation parameter of the preset fault of the cloud virtual gateway system exceeds the log opening threshold value, responding to the fact that the operation parameter exceeds the log opening threshold value, opening a network flow log, and storing the acquired network flow log to a bypass storage device locally, wherein the bypass storage device is not connected with devices in the cloud virtual gateway system in series. The predetermined failure may include a failure related to a decrease in forwarding quality, and such a failure may cause a user to be affected when using the cloud virtual gateway service, for example, a TCP (Transmission Control Protocol) packet loss or a large number of retransmissions. A TCP packet loss threshold and a retransmission threshold may be preset, and when it is monitored that the TCP packet loss reaches the predetermined threshold or the retransmission exceeds the predetermined threshold, the network flow log is started.
In some other embodiments, the network flow log opening of a specific data flow may be used, and specifically, the network flow log detecting manner may include: determining a preset service data flow for starting a network flow log; and when the preset service data stream is monitored, starting a network stream log, and storing the obtained network stream log to a bypass storage device locally, wherein the bypass storage device is not connected with the device in the cloud virtual gateway system in series. The predetermined data stream may be one or more of various service data streams running in the cloud virtual gateway system, and may be set according to specific service needs.
In still other embodiments, both types of webflow logs described above, either based on a particular failure or a particular data flow, may be opened simultaneously.
In view of the fact that a network flow log detection mode is started in real time, the storage capacity is large, the cost of storage equipment is high, and adverse effects are generated on service flows of the cloud virtual gateway system, the network flow log in the embodiment of the invention is not stored on the cloud virtual network system, but a bypass storage mode is adopted, namely, the network flow log obtained after the network flow log is started is stored on third-party equipment which is not connected with node equipment of the cloud virtual gateway system in series, and the effects on service processing of the cloud virtual gateway system are reduced. Further, for the network flow log stored on the bypass device, a storage time limit may also be set, that is, the network flow log for the bypass device is deleted at regular time. The network flow logs of the bypass equipment are stored, so that the fault location of the cloud virtual gateway system can be facilitated, but the storage capacity of the network flow logs is huge, and the requirements of fault detection and storage cost are well balanced by setting storage time limit in consideration of the problem of storage equipment cost.
Next, a health check detection mode is introduced.
The health check probing manner may include bypassing probing a particular cloud virtual gateway server by a predetermined instruction. In some specific embodiments, the predetermined instructions may include: ping, telnet, etc. The specific cloud virtual gateway server can comprise a functional gateway such as an NAT gateway, a private line gateway and a VPN gateway, and different gateway servers can be used in different application scenarios.
Ping may be used for procedures to test the amount of network connections, typically commands to check if the network is clear or the speed of the network connection, and Ping domain names may also be used to derive a resolved IP address. It is sufficient to use ping ip address (web address). ping is primarily an end-to-end connection, enabling checks for availability.
The Telnet protocol is one of TCP/IP protocol family, is a standard protocol and a main mode of Internet remote login service, is commonly used for remote control of a web server, and can be used for a user to execute work on a remote host at a local host. First, a Telnet program is executed on a computer, a connection is made to a destination server, and then an account number and a password are input to verify the identity. The user may enter commands at the local host and then have the remote host establish a connection perform as if it were entered directly at the opposite console.
In some embodiments of the invention, the bypass detection may further comprise: and performing bypass detection on the host machine outlet forwarding of the cloud server, the outlet and inlet forwarding of the cloud virtual gateway server and the cloud boundary outlet and inlet forwarding. The cloud boundary gateway refers to a cloud boundary switch (i.e., a network device at the boundary of iaas layer cloud). The method solves the trouble of starting the network flow log at the user side to a certain extent, avoids the influence of the resource occupation of the network flow log on the service of the user, and facilitates the subsequent automatic and rapid positioning of the fault position and the fault reason.
And thirdly, introducing a detection mode of the bale plucking tool.
In some embodiments of the invention, the bale plucker detection mode comprises: and (4) using a preset tool to grab the packet according to different encapsulation settings. The predetermined bale grabbing tool can comprise a bale grabbing tool such as tcpdump, the bale grabbing result is analyzed by an analysis tool such as wireshark, and the analysis result is output so as to locate the fault position and the fault reason. the tcpdump packet capturing tool can enter parameters such as source IP, destination IP, source port, destination port, packet capturing interval, packet capturing duration, packet capturing granularity and the like, and automatically sets configuration such as packet capturing offset and the like according to parameters. For example, offset settings may be made for different encapsulations, according to different source IPs, to grab the target packet. the tcpdump toolkit intercepts the data packets on the network according to the definition of a user, and can completely intercept the header (header part) of the data packets transmitted in the network to provide analysis. the tcpdump toolkit supports filtering for network layer, protocol, host, network or port and provides logical statements like and, or, not, etc. to filter garbage. Directly starting tcpdump may monitor all the packets flowing through the first network interface, monitor the packets of the specified host, specify IP, for example, capture all the packets received and sent by all the hosts with IP addresses x.y.z.t, obtain all the packets communicated by the first host and other hosts except the second host, and specify the packets of the network, etc.
The embodiment of the invention aims at specific fault scenes and service scenes, automatically schedules corresponding detection and inspection modes when faults occur, and processes and analyzes the corresponding network nodes. For example, for a failure associated with a particular traffic data flow, a manner of starting a weblog probe according to the particular data flow may be first employed. For a specific fault, a network flow log detection mode can be started according to the specific fault. For other types of faults, the health check detection mode or the bale plucker detection mode of the detection mode can be adopted firstly. It should be noted that the embodiment of the present invention is not particularly limited to this.
The three detection modes can be selected correspondingly according to the fault scene and the corresponding network topology. In some specific embodiments, the three detection modes may be integrated on an operation and maintenance tool integration platform as shown in fig. 3. The detection results of the three detection modes can be output and presented on the operation and maintenance tool integration platform, and the detection results are stored on the integration platform and are not stored in series with the cloud virtual gateway system, that is, the storage of the fault detection result is independent of the service flow of the user, so that the influence on the service of the user is avoided.
According to the method, the device and the storage medium for locating the fault of the cloud virtual gateway, provided by the embodiment of the invention, by monitoring the running state in the cloud virtual gateway system and generating the network topology of the cloud virtual gateway system according to the scene information associated with the fault when the fault is monitored, conditions are provided for accurate and convenient fault location, and convenience is provided for service influence analysis and fault isolation under a fault scene; the method of node equipment bypass detection is adopted, so that the influence of the resource occupation of the network flow log on the service of the user is avoided; in view of the defects that the existing network flow logs have large storage capacity and cannot be started in real time, a mode of triggering and starting a specific fault point and a service flow is adopted, so that the storage pressure in fault positioning is reduced, and meanwhile, the network flow logs are stored in a bypass mode, so that the influence on the service flow of the cloud virtual gateway is reduced; according to the invention, by acquiring and generating the network topology of the user service scene and calling the bypass of the detection and inspection module, the processing and analysis at the corresponding node are automatically carried out and the result is output when the fault scene occurs.
The embodiment of the invention also provides computer equipment. As shown in fig. 4, the computer device 400 may comprise a memory 401 and a processor 402, wherein the memory 401 stores computer instructions and the processor 402 is configured to execute the computer instructions to cause the computer device 400 to implement the method described above.

The servers can also be used for realizing the functions of the operation and maintenance tool integration platform, and are used for detecting faults through detection modes such as network flow logs, health check and packet capturing tools and the like. The fault location server system or the computer device provided by the embodiment of the invention is not connected in series with the cloud virtual gateway system, that is, the fault location server system or the computer device is independent of the cloud virtual gateway system, and the fault location detection result is independent of the service data stream of the cloud virtual gateway system, so as to ensure that the fault location detection result (for example, a large-capacity network stream log and the like) does not affect the normal service of the cloud virtual gateway system.
