Referring to FIG. 2 , it is a flowchart of a method for detecting a connection state provided by an embodiment of the present application. The method specifically includes the following procedures.

201. The monitoring host 101 collects information about the source node 103 of the host 102 and generates a detection list. 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 . Collect the network information of each source node 103 according to the IP address of each host 102 collected by the monitoring host 101, and generate a detection list, which includes: the source node 103 of each host 102, each source node 103 Multiple network interfaces and multiple target nodes, wherein each network interface corresponds to at least one target node.

The monitoring host 101 collects the IP address of the first host, and according to the IP address of the first host, the IP address of the first host is The network information of the source node 103 is collected. the network The 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 .

In yet 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 only one source node 103 can exist in a group. Source node groups represent source nodes of the same role or function. For example: Compute group, Control group, Network group, Storage group, each group includes multiple subgroups, for example, Compute1 group to Compute n, Controll group to Control n group, Network1 to Network n group. Among all the source node groups, the user determines the source node group to be detected from multiple source node groups through the monitoring host 101 .

In at least one embodiment of the present application, determining the network interface to be detected of each source node 103 in the source node group to be detected includes: in this embodiment, the network interface exists on the source node 103, A source node 103 has multiple network interfaces, for example: Interface1, Interface2. The user determines the network interface to be detected through the monitoring host 101 .

For example, the source node 103 network information in the correct format is collected as follows: 127.xxx.xxx.x/xx dev<interface name>proto kernel scope link src<ip>. Among them, 127.xxx.xxx.x/xx represents the IP address of the target node, and interface name represents the network interface.
