and executing the code generation statement to generate an ID code, and determining the ID code as the link tracking ID of the target link.
In detail, the unique encoding function includes, but is not limited to, a GUID function.

Further, the embodiment of the present invention combines the node IP identifiers of the adjacent nodes in the target link into a hierarchical IP, so as to mark the hierarchical relationship between the adjacent nodes in the target link by using the hierarchical IP. For example, if there are neighboring nodes E and R in the target link, the node IP of node E is identified as 123.456.7.8, and the node IP of node R is identified as 321.654.8.7, then the node IP identifications of node E and R are combined into a hierarchy IP: 123.456.7.8-321.654.8.7, using hierarchical IP: 123.456.7.8-321.654.8.7 mark the hierarchical relationship between neighboring nodes E and R.
Preferably, when the node IP identifiers of the adjacent nodes in the target link are combined into the hierarchical IP, the node IP identifiers may be combined according to the hierarchical relationship between the adjacent nodes in the target link. For example, if the hierarchy between the neighboring node E and the node R calls the node R for the node E, the node IP identities of the node E and the node R are combined into a hierarchy IP: 123.456.7.8-321.654.8.7; if the hierarchical relationship between the adjacent node E and the node R is that the node R calls the node E, combining the node IP identifications of the node E and the node R into a hierarchical IP: 321.654.8.7-123.456.7.8.

The target link tracing request comprises a request header and a request body, wherein the request header is used for storing a layer level IP and tracking the node state in the target link, and the request body is used for storing a link tracing ID and tracking the complete state of the target link in the distributed system.
For example, the target link trace ID is 1xxxxx 0; the IP level is 123.456.7.8-321.654.8.7; 123.456.7.8-321.654.8.7 are written into the request header, and 1xxxxx0 is written into the request body, so as to obtain the link trace statement.
S6, executing the link tracing statement to acquire the state of the node marked with the link tracing ID in the target link.
In this embodiment of the present invention, the executing the link trace statement to obtain the state of the node marked with the link trace ID in the target link includes:
constructing a tracking time rule by using a user-defined processing function;
and executing the link tracking statement according to the tracking time rule to acquire the state of the node marked with the link tracking ID in the target link.
In detail, the custom processing function includes, but is not limited to, one or more of the following:
an IF function for determining a tracking condition;
the TO _ DATE function, used TO represent the DATE;

acquiring a user-defined processing function corresponding to preset tracking time;
detecting a compiling environment of the distributed system;
compiling the user-defined processing function through a compiler corresponding to the compiling environment to obtain the tracking time rule.
In the embodiment of the invention, the state of marking the link tracking ID in the target link of the distributed system can be tracked according to the tracking time rule by constructing the custom processing function, so that the problem of low tracking efficiency caused by occupying a large amount of system resources due to frequent or continuous tracking is avoided.
The embodiment of the invention realizes the automatic marking of the nodes of the target link by acquiring the hierarchical relationship between a plurality of nodes in the target link and each node, generating the tracking ID of the target link, marking the plurality of nodes in the target link as the tracking ID of the target link, acquiring the node IP identification of each node in the target link, and combining the node IP identifications of adjacent nodes in the target link into the hierarchical IP, without configuring the IP of the nodes and the ID of the link to which the nodes belong according to the self attribute of the distributed system before each node of the target link, thereby avoiding the problem that the IP of the nodes and the ID of the link to which the nodes belong need to be reconfigured according to different distributed systems when the link node state is called in different distributed systems, and improving the portability of the link tracking method.
