[0002] When managing network cluster nodes, it is necessary to ensure that the connection status between each node is normal so that the node's application services can operate normally. When it is necessary to detect the connection status of the node, the host responsible for monitoring often needs to issue a large number of detection instructions to multiple nodes. The loading and running of a large number of programs will inevitably cause the host's resources to be occupied in large quantities and affect the host's normal execution of other tasks. Existing detection of the connection status of nodes usually requires manual establishment of a node detection list. When the number of source nodes is large, manually establishing a detection list is extremely time-consuming and inefficient. Furthermore, after the host issues a detection instruction, each node directly obtains the connection status.

[0020] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the present application is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present application. The embodiments described are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0023] The connection status detection method provided in the present application can be used for connection status detection between nodes, and the method runs on a monitoring host.

[0024] See also Figure 1 1 is a schematic diagram of a connection between a monitoring host and multiple hosts provided in an embodiment of the present application. A monitoring host 101 is in communication connection with multiple hosts 102 , and each host 102 includes a source node 103 .

[0025] The monitoring host 101 is used to control each host 102, and the host 102 provides an IP address for the source node 103. In one embodiment, the IP address of the host 102 is the IP address of the source node 103.

[0026] In one embodiment, a host 102 includes a source node 103 , and each source node 103 corresponds to a host 102 .

[0027] See also Figure 2 FIG. 1 is a flow chart of a connection status detection method provided in an embodiment of the present application. The method specifically includes the following process.

[0028] 201. The monitoring host 101 collects information of the source node 103 of the host 102 and generates a detection list.

[0029] In at least one embodiment of the present application, the monitoring host 101 collects the IP address of each host 102, that is, the IP address of each source node 103. Each host 102 is a host managed by the monitoring host 101. According to the IP address of each host 102 collected by the monitoring host 101, the network information of each source node 103 is collected, and a detection list is generated, wherein the detection list includes: the source node 103 of each host 102, multiple network interfaces of each source node 103, and multiple target nodes, wherein each network interface corresponds to at least one target node. For example, the IP address of the first host managed by the monitoring host 101 is: 127.132.128.64, the monitoring host 101 collects the IP address of the first host, and addresses according to the IP address of the first host, and collects the network information of the source node 103 on the first host. The network information includes: the network interface of each source node 103, and the IP address of the target node connected to the network interface of each source node 103.

[0030] In another embodiment of the present application, multiple source node groups are set according to all source nodes 103 in the detection list, each source node group includes at least one source node 103 and a source node 103 can only exist in one group. Source node groups represent source nodes with the same role or function. For example: Compute group, Control group, Network group, Storage group, each group includes multiple sub-groups, for example, Compute1 group to Computen, Control1 group to Control n group, Network1 to Network n group. Among all source node groups, the user determines the source node group to be detected from multiple source node groups by monitoring the host 101.

[0031] In at least one embodiment of the present application, determining the network interface to be detected of each source node 103 in the group of source nodes to be detected includes:

[0032] In this embodiment, the network interface exists on the source node 103 , and one source node 103 has multiple network interfaces, for example, Interface 1 and Interface 2 . The user determines the network interface to be detected through the monitoring host 101 .

[0033] In at least one embodiment of the present application, at least one is selected from the source nodes 103 of each host 102 in the detection list as the source node to be detected. For example, the user selects 20 source nodes 103 as the source nodes to be detected by monitoring the host 101, and the detection list only includes the network interfaces to be detected of the selected 20 source nodes and the target nodes connected to the network interfaces to be detected. Further, the target nodes in the closed state or maintenance state in the detection list can be eliminated to update the detection list. The target nodes eliminated in the detection list may come online again at some time, and when the eliminated target nodes come online again, these target nodes can be rejoined in the detection list. Among them, the source nodes in the source node group to be detected can be selected as the source nodes to be detected, or the source nodes to be detected can be selected according to the IP addresses of the source nodes.

[0034] 202. Store the detection list on the source node to be detected.

[0035] In at least one embodiment of the present application, the monitoring host 101 uses an asynchronous method and stores the detection list on the source node to be detected through the rsync synchronization tool. The rsync synchronization tool can synchronously update files and directories of two computers (for example, the monitoring host 101 and the host 102 in the embodiment of the present application), and appropriately use differential encoding to reduce the amount of data transmission. Because the source node 103 exists on the host 102, the detection list existing in the monitoring host 101 can be synchronously updated to the source node to be detected on the host 102 using the rsync synchronization tool.

[0036] 203. Send a network detection instruction to the source node to be detected, detect the connection status between the source node to be detected and the target node corresponding to the source node to be detected, and obtain a detection result.

[0037] In at least one embodiment of the present application, the monitoring host 101 controls the source node to be detected to determine at least one target node corresponding to the source node to be detected according to the detection list, and reads the content of the detection list according to the network detection request, and detects the connection status between the source node to be detected and at least one target node corresponding to the source node to be detected in an asynchronous manner to obtain a detection result. For example, the following is an example of a detection result in JSON format:

[0038] {"Name 1[\<target node 1 IP>\"],\"<network interface 1>"\:"<detection result>",

[0039] "Name 2 [\<target node 2 IP>\"], \"<network interface 1>"\: "<detection result>",

[0040] …

[0041] "Name n [\<target node n IP>\"], \"<network interface n>"\: "<detection result>",

[0042] }.

[0043] 204. Analyze the detection result and the detection list to determine that the detection result is the cause of the connection failure.

[0044] If it is detected that the source node to be detected fails to connect to at least one of the target nodes through the first network interface, and it is detected that the source node to be detected successfully connects to the target node through the second network interface, it is determined that there is a problem with the first network interface of the source node to be detected.

[0045] For example, the following is the connection status detection result of the source node and the target node to be detected:

[0046] Table 1

[0047]

[0048] Table 2

[0049]

[0050] Table 3

[0051]

[0052] Table 4

[0053]

[0054]

[0055] Table 5

[0056]

[0057] Table 6

[0058]

[0059] Note: N indicates that the connection status between the source node to be detected and the target node in the source node group to be detected is failed.

[0060] Y indicates that the connection status between the source node to be detected and the target node in the source node group to be detected is successful.

[0061] From Table 1 above, it can be seen that in Interface 1, all Compute groups failed to connect to all target nodes. From Table 2, it can be seen that in Interface 2, all Compute groups successfully connected to all target nodes. Therefore, it is determined that the source nodes to be detected in all Compute groups have problems in Interface 1.

[0062] From Table 3 above, it can be seen that in Interface1, the Compute1 group in the Compute group fails to connect to all target nodes, resulting in the target nodes of Compute1 also failing to connect to other groups. From Table 4, it can be seen that in Interface2, the Compute1 group in the Compute group successfully connects to all target nodes, thus determining that the source node to be detected in the Compute1 group in the Compute group has a problem in interface1.

[0063] It can be seen from Table 5 above that in Interface 1, the Compute group, Control group, Network group, and Storage group failed to connect to all target nodes. It can be seen from Table 6 that in Interface 2, the Compute group, Control group, Network group, and Storage group successfully connected to all target nodes. Therefore, it is determined that there are problems with the Compute group, Control group, Network group, and Storage group in Interface 1.

[0064] See also Figure 3 As shown, it is a flowchart of collecting network information of each source node 103 provided in an embodiment of the present application.

[0065] In at least one embodiment of the present application, the monitoring host 101 sends a collection instruction to each of the source nodes 103 through the Secure Shell (SSH) protocol, notifying each of the source nodes 103 to start collecting its own network information. The SSH protocol is an encrypted network transmission protocol that can provide a secure transmission environment for network services in an unsafe network. SSH establishes a secure tunnel in the network to achieve a connection between the SSH client and the server. SSH is usually used to transmit a command line interface and remotely execute commands. Through the SSH protocol, the monitoring host 101 can safely and stably send collection instructions to all source nodes 103.

[0066] 301. Collect network information according to the IP address of each source node 103 and detect whether the format of the network information is correct.

[0067] In at least one embodiment of the present application, the network information of all source nodes 103 is collected by collecting the IP address of the host 102 where each source node 103 is located. The collection of network information is achieved through the CollectVlanIPTable script. In addition to collecting and collating the network information of the source node 103, the CollectVlanIPTable script also detects the format of the collected network information and generates a JSON format file. For example, the following is the network information of the source node 103 collected in the correct format:

[0068] 127.xxx.xxx.x / xx dev<interface name> proto kernel scope link src <ip>.

[0069] Among them, 127.xxx.xxx.x / xx represents the IP address of the target node, and interface name represents the network interface.

[0070] 302. The monitoring host 101 controls each of the source nodes 103 to obtain parsed information from the network information in the correct format and convert the parsed information into a JSON format file.

[0071] In at least one embodiment of the present application, if the format of the network information is incorrect, the monitoring host 101 controls each of the source nodes 103 to determine that the network information is invalid. If the format of the network information is correct, the monitoring host 101 controls each of the source nodes 103 to obtain parsing information from the network information, the parsing information including the network interface of each of the source nodes 103 and the IP address of the target node connected to the network interface of each of the source nodes 103, and controls each of the source nodes 103 to convert the parsing information into a JSON format file.

[0072] To illustrate, the following is an example of converting parsed information into a JSON format file:

[0073] {"interface":"<interface 1> ","ip":"<172.168.64.32>"}.

[0074] 303 . Controlling each of the source nodes 103 to serialize the JSON format file into a string type file includes: the monitoring host 101 receives the string type file of each of the source nodes 103 .

[0075] 304. The monitoring host 101 merges the string type files according to the JSON format.

[0076] See also Figure 4 As shown, it is a connection status detection flow chart provided in an embodiment of the present application, which specifically includes the following:

[0077] The monitoring host 101 initiates a network detection request to the source node to be detected.

[0078] 401. Control the source node to be tested to read the content of the detection list according to the network request, perform network detection and obtain the detection result.

[0079] In this embodiment, the source node to be detected is controlled to read the content in the detection list according to the network detection request, and the connection status between the source node to be detected and at least one target node is detected in an asynchronous manner to obtain a detection result.

[0080] 402. Control the source node to be detected to store the detection result in JSON format.

[0081] The monitoring host 101 receives the JSON format returned by the source node to be detected.
