Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
With the development of network technologies such as internet, cloud computing, big data and the like, the importance of a data center is gradually increased, and the number and the types of physical devices included in the data center are continuously increased, which not only increases the complexity of the internal network environment of the data center, but also provides a serious challenge for the management of the physical devices. In the related art, physical devices in a data center are easy to be added and replaced, but after the physical devices access an internal network, it is difficult to perform automatic discovery and automatic inclusion management on the physical devices, so how to implement automatic discovery on the physical devices in the data center is a technical problem to be faced by those skilled in the art. In view of this, the present invention provides an apparatus discovery method, which can scan a port of an IP address of an apparatus to be scanned, determine whether the apparatus is online and the port used by the apparatus, acquire apparatus information from a physical apparatus through the port, and further determine an accurate identity of the physical apparatus through the apparatus information, thereby implementing automatic discovery of the physical apparatus and effectively improving operation and maintenance efficiency. Referring to fig. 1, fig. 1 is a flowchart of a device discovery method according to an embodiment of the present invention, where the method includes:
s101, obtaining an IP address of the equipment to be scanned.
It should be noted that the embodiment of the present invention does not limit the source of the IP address of the device to be scanned, and for example, the source may be from a preset IP address field, or from a preset IP address list, and the source may be selected according to the actual application requirement. In view of the fact that the preset IP address list can accommodate more IP addresses, in the embodiment of the present invention, the IP address can be obtained from the preset IP address list. The embodiment of the present invention also does not limit the setting mode of the preset IP address list, and for example, the preset IP address list may be prestored in a memory of an apparatus discovery device executing the apparatus discovery method, or may be issued by a separate configuration management device, where the configuration management device is used to centrally manage IP addresses in an intranet environment of a data center, and issue IP addresses to be scanned for the apparatus discovery device. In consideration of the fact that the network environment in the data center is complex, the number of physical devices is large, and the types of physical devices are many, the IP addresses are managed and issued in a centralized mode by adopting the independent configuration management device, the configuration efficiency of the device discovery device can be effectively improved, the scanning range of the device discovery device is improved, and then the cost of operation and maintenance of the device is effectively reduced.
Furthermore, the embodiment of the present invention does not limit whether the device discovery apparatus periodically obtains the IP address from the preset IP address list, and when a single scan of the IP address can discover a sufficient amount of physical devices, that is, can meet the application requirements, the obtaining step does not need to be performed periodically; when flexibility of device discovery needs to be improved, and it is ensured that each online physical device can be effectively discovered, the IP address can be periodically obtained from the preset IP address list. In the embodiment of the invention, in order to ensure that each online physical device can be effectively discovered and recorded, the IP address can be periodically acquired from the preset IP address list. It should be noted that, the embodiment of the present invention does not limit the specific cycle value, and the cycle value may be set according to the actual application requirement.
In one possible scenario, acquiring an IP address of a device to be scanned includes:
step 11: and receiving a preset IP address list issued by the configuration management device, and periodically acquiring the IP address from the preset IP address list.
S102, carrying out port scanning on the IP address, and determining a port used by equipment to be scanned;
it should be noted that, the embodiments of the present invention do not limit the specific manner and process of port scanning, and refer to the related art of port scanning. It can be understood that, when the port opened by the device to be scanned is scanned, the response information returned by the device can be received, and the port used by the device to be scanned can be determined according to the information. The embodiment of the present invention does not limit the specific form of the response information, and reference may be made to the related art of port scanning. Of course, if the response information of the device to be scanned is not received, the device has no response, and at this time, there may be a case where the device is offline, crashed, or the port is not opened, and the device discovery process for the device may be exited. The embodiment of the present invention does not limit the specific step of determining that the device to be scanned does not respond, and for example, a preset time period may be set, and if the response time of the device to be scanned exceeds the preset time period, it is indicated that the device does not respond, and at this time, the device discovery process of the device may be exited. The embodiment of the invention does not limit the specific value of the preset time period, and can be set according to the actual application requirement.
Further, the embodiment of the present invention does not limit which ports of the IP address are scanned, and the scanning can be set according to specific application requirements. In particular, since the ports generally correspond to a communication protocol, the corresponding ports to be scanned may be determined according to the communication protocol commonly used by the physical devices in the data center. It can be understood that the equipment of the data center mainly consists of servers and disk array equipment. For the server, the device usually supports two communication protocols, i.e. an IPMI Protocol and an SNMP Protocol, where IPMI (Intelligent Platform Management Interface) is an industrial communication standard, the Protocol uses UDP623 port for communication, and UDP (User data Protocol) is a transmission Protocol; SNMP (Simple Network Management Protocol) is a standard Protocol specifically designed for managing Network nodes (servers, workstations, routers, switches, HUBS, etc.) in an IP Network, and the Protocol uses UDP161 port for communication, so if a server device needs to be identified, UDP623, UDP161, or a combination of UDP623 and UDP161 can be scanned; for the raid device, the device usually supports two communication protocols, i.e. an SNMP Protocol and an SMI-S Protocol, where SMI-S (Storage Management Initiative specification) is a standard Management Protocol for monitoring and managing the Storage device, the Protocol uses TCP5989 port for communication, and TCP (Transmission Control Protocol) is also a Transmission Protocol, so that if the raid device needs to be identified, TCP5989, UDP161, or a combination of TCP5989 and UDP161 may be scanned. Of course, if all servers and disk array devices need to be completely covered, the combination of the ports UDP623, UDP161, and TCP5989 may also be scanned, so as to ensure that the physical devices that have been brought online inside the data center are effectively discovered. S103, acquiring equipment information from the equipment to be scanned by using the general interface of the port corresponding to the communication protocol and the default configuration information of the communication protocol.
After the port used by the device to be scanned is determined, the specific device information can be acquired from the device to be scanned by using the universal interface of the communication protocol according to the corresponding relationship between the port and the communication protocol. It should be noted that the embodiment of the present invention does not limit how to obtain the device information from the device to be scanned by using the general interface of the communication protocol, and refer to the related technologies of IPMI, SNMP, and SMI-S. It can be understood that various communication protocols are provided with a security check mechanism, so that when the device information is acquired from the device to be scanned, the configuration information of the protocol needs to be carried. In the embodiment of the invention, the equipment information is acquired by adopting the default configuration information universally configured by the communication protocol, wherein the default configuration information is the configuration information carried by the physical equipment when the physical equipment leaves a factory or the communication protocol is initialized. It is understood that the default configuration information of different communication protocols is different, so that the corresponding default configuration information can be selected according to the specific communication protocol, for example, for the IPMI protocol, the default configuration information is usually a default user name and a default password; for the SNMP protocol, its default configuration information is typically the default Community name (Community); for the SMI-S protocol, the default configuration is usually a default user name, a default password and a default Namespace (Namespace), and the related technology of the corresponding protocol can be referred to for the specific content of the default protocol configuration of each protocol.
Further, if the device to be scanned communicates using the IPMI protocol, the device information of the device is usually stored in FRU information, where the FRU information includes device information such as device manufacturer, signal, serial number, and the like, so that the FRU information may be requested from the device to be scanned to extract the corresponding device information.
In a possible case, when the port is UDP623, acquiring device information from the device to be scanned by using a general interface of the port corresponding to the communication protocol and default configuration information of the communication protocol, which may include:
step 21: acquiring FRU information from the equipment to be scanned by using a universal interface of an IPMI protocol and default configuration information, and extracting equipment information from the FRU information; the default configuration information includes a default username and a default password.
It should be noted that the embodiment of the present invention does not limit the specific manner of acquiring FRU information, and reference may be made to the IPMI protocol and the technology related to ipmitool. The embodiment of the present invention also does not limit the specific content of the device information extracted from the FRU information, and may include, for example, information such as a device serial number, a device model, a device manufacturer, and the like, and may further include motherboard information, a device version, a device asset serial number, and the like, and may be selected according to information that can be provided by the FRU and in combination with specific application requirements.
Further, if the device to be scanned communicates using the SMI-S protocol, the device Information of the device is usually stored in CIM Product Information (CIM _ Product), where CIM (Common Information Model) is a standard used in the computer industry to define devices and application modes, and the CIM Product Information includes device Information such as device manufacturer, signal, serial number, etc., so that the CIM Product Information can be requested from the device to be scanned to extract the corresponding device Information.
In a possible case, when the port is TCP5989, acquiring device information from the device to be scanned by using a common interface of the port corresponding to the communication protocol and default configuration information of the communication protocol, including:
step 31: acquiring CIM product information from the equipment to be scanned by using a universal interface of an SMI-S protocol and default configuration information, and extracting equipment information from the CIM product information; the default configuration information includes a default username, a default password, and a default namespace.
It should be noted that the embodiment of the present invention does not limit the specific way of acquiring the FRU information, and reference may be made to the related art of the SMI-S protocol. The embodiment of the present invention also does not limit the specific content of the device information extracted from the CIM product information, and may include, for example, information such as a device serial number, a device model, a device manufacturer, and the like, and may further include a device name, a device profile, a device version, and the like, and may be selected according to information that can be provided by the CIM product information and in combination with specific application requirements.
Further, if the device to be scanned communicates using the SNMP protocol, the device Information of the device is usually stored in a MIB (Management Information Base), such as a common MIB (RFC-1213-MIB, which may also be referred to as MIB-II object group) and an Entity MIB (Entity MIB), where a System group (System group) of the common MIB stores a System object ID (sysobjectid) that is a unique identifier set by a manufacturer for each type of device, so that a device table may be preset, where a plurality of System object IDs and corresponding vendor Information and model Information are stored in the device table, and the vendor Information and model Information of the device to be scanned are matched in the device table by using the System object ID of the device to be scanned, so as to determine the vendor Information and model Information of the device; the actual MIB contains the device serial number (usually stored in the physical serial num field of the physical MIB). Since the MIB library generally uses an Object Identifier (Object Identifier) for data management, a preset Object Identifier may be used to obtain corresponding data in the MIB library. Specifically, in the common MIB, the OID, 1.3.6.1.2.1.1.3.0, is typically used to obtain the sysObjectId, while in the entity MIB, the OID, 1.3.6.1.2.1.47.1.1.1.1.11, is typically used to obtain the device serial number. Of course, since other device information, such as device version information, is also stored in the common MIB and the entity MIB, other device information may also be obtained from the MIB, and may be selected according to actual application requirements.
In a possible case, when the port is UDP161, acquiring device information from the device to be scanned by using a general interface of the port corresponding to the communication protocol and default configuration information of the communication protocol, including:
step 41: acquiring a system object ID in a public MIB (management information base) of equipment to be scanned by utilizing a general interface, default configuration information and a first preset object identifier of an SNMP (simple network management protocol), and acquiring serial number information in an entity MIB of the equipment to be scanned by utilizing the general interface, the default configuration information and a second preset object identifier; the default configuration information includes a default group name;
step 42: matching the preset equipment table with the system object ID to obtain manufacturer information and model information of the equipment to be scanned; a plurality of system object IDs, corresponding manufacturer information and model information are arranged in the preset equipment table;
step 43: and setting the manufacturer information, the model information and the serial number information as equipment information.
And S104, updating the equipment information to a database.
It should be noted that the device information updating operation may be performed by the device discovery apparatus, or may be performed by another separate asset management apparatus. In the embodiment of the present invention, in order to save the computing resources of the device discovery apparatus, in the embodiment of the present invention, the asset management apparatus may be used to update the device information, and the device discovery apparatus only needs to send the acquired device information to the asset management device. In order to improve the processing efficiency of the asset management device, a blocking queue can be arranged in the asset management device, and the device discovery device needs to send the device information to the blocking queue, so that the asset management device can extract the device information from the blocking queue and further execute a corresponding updating step. It should be noted that, the embodiment of the present invention does not limit the setting manner of the congestion queue, and reference may be made to related technologies. Also, to ensure that the asset management device properly processes the device information, the device information update may be performed using a single thread.
In one possible scenario, updating the device information to a database includes:
step 51: and sending the equipment information to the asset management device so that the asset management device adds the equipment information to the database when determining that the equipment to be identified is new equipment by using the equipment information.
It should be noted that, the embodiment of the present invention does not limit how to determine whether the device to be identified is a new device by using the device information, for example, the device serial number in the device information may be used for matching, if not, the device serial number is determined as the new device, of course, all information in the device information may be used for complete matching, and if not, the device serial number is determined as the new device, and the setting may be performed according to the actual application requirement.
Finally, if the device discovery apparatus obtains the IP address from the preset IP address list, in order to avoid repeated scanning, the device discovery apparatus may move the corresponding IP address out of the preset IP address list after the device information is updated to the database.
In one possible case, after updating the device information to the database, the method may further include:
step 61: and moving the IP address out of the preset IP address list.
Based on the above embodiment, the present invention firstly performs port scanning on the IP address of the device to be scanned, and the scanning operation can determine not only whether the device is online, which is convenient for finding the online device in time, but also determine the port used by the device. Because the corresponding relation exists between the port and the communication protocol, the communication protocol supported by the equipment can be further determined according to the port used by the equipment to be scanned, and then the equipment information capable of uniquely identifying the equipment can be acquired from the equipment to be scanned by utilizing the universal interface and default configuration information of the communication protocol, so that the automatic discovery and automatic identification of the equipment to be scanned are finally realized, the working efficiency of operation and maintenance personnel can be effectively improved, and the operation and maintenance cost can be effectively reduced.
The device discovery method described above is described below based on a specific flowchart. Referring to fig. 2, fig. 2 is a flowchart of another device routing method according to an embodiment of the present invention, where the method includes:
1. extracting an IP address from an IP list to be detected issued by a configuration management device; the IP list to be detected is obtained by dividing the configuration manager according to the network planning of the current data center;
2. carrying out port scanning on UDP623, UDP161 and TCP5989 ports of the IP address, and determining a port used by equipment to be scanned;

6. And sending the equipment information to a data blocking queue of the asset management device so that the asset management device adds the equipment information to the database when determining that the equipment to be identified is new equipment by using the equipment serial number in the equipment information.
