step S1, a distributed application unique identifier is obtained.
Before the unique identifier of the distributed application is acquired, the unique identifier and the name of the application of the distributed application are recorded. The application unique identifiers must not be the same for different distributed applications. For different nodes of the distributed application, the modes of the same application identifier and different application names can be adopted.
And step S2, injecting a link tracking code into the program of the distributed application by using a byte code enhancement technology according to the unique identifier of the distributed application.
The link tracking code comprises an interceptor code and an enhancement code, and is injected into a program of the distributed application. Specifically, by adopting bytecode enhancement and a JVMTI interface technology, link trace codes of distributed transactions are injected during the loading of distributed application classes, and the injected link trace codes can add application-level identifiers as associations between messages when messages are transmitted between nodes of distributed applications.
And step S3, collecting the program, the link calling process and the calling stack information of each distributed application by using the link tracking code.
Specifically, during case execution, a method of injecting link trace code is invoked, wherein the injected interceptor code performs a distributed link program acquisition across applications according to the identifiers of the applications. The injected enhanced code can add application-level identifiers as associations between messages when message passing occurs between nodes of the distributed application, so as to track call link processes between applications and between nodes, as shown in fig. 2. In fig. 2, Node1 and Node2 belong to the Node of application a, Node3 and Node4 respectively belong to the Node of application b, the whole calling link completes a transaction with the transaction number Txid, and the scheduling relationship between the nodes is labeled by using SpanId and pSpanId, so that the labeling of the calling relationship across applications is completed.
And step S4, distinguishing the call relation among the distributed applications according to the programs, the link call process and the call stack information of the distributed applications to form a link call complete process.
Specifically, after the link calling process and the call stack information of each distributed application are collected and analyzed according to fig. 2 by using the link tracking code, the completed link calling process can be formed by distinguishing the calling relationship between the applications.
As one embodiment of the invention, the link trace code includes an interceptor code and an enhancement code.
In this embodiment, the collecting, by using the link tracking code, the program, the link calling procedure, and the call stack information of each distributed application includes: collecting a program of a distributed application by using the interceptor code; and adding an application level identifier in the message transmission process of each distributed application by using the enhanced code, and acquiring a path calling process and calling stack information of each distributed application by using the application level identifier.
Wherein the injected interceptor code performs a distributed link program acquisition across the application according to the identifier of the application. The injected enhanced code can add application-level identifiers as associations between messages when message passing occurs among nodes of the distributed application, so that calling link processes among applications and among nodes are tracked.
As an embodiment of the invention, the method further comprises: and calling a complete process for the programs and the links of the distributed applications in an asynchronous data transmission mode to perform distributed data storage.

Specifically, the control management module 1 is configured to implement functions of management of deployed distributed applications, control switch management, application probe management, and the like. To implement the acquisition of the cross-application distributed link program and case contrast relationship of the deployed distributed application, the following steps are firstly completed: 1) and entering an application unique identifier and a name of the distributed application. The application identifiers must not be the same for different distributed applications. For different nodes of the distributed application, the modes of the same application identifier and different application names can be adopted. 2) A unique identifier, location, version of the application probe is defined. 3) The acquisition frequency of the distributed application is defined, i.e. the procedure deciding whether to acquire the distributed call link procedure partially or fully. 4) And setting the distributed call link acquisition switch to be in an opening state.

And injecting link tracking and intercepting codes of distributed transactions during the loading of the distributed application classes, wherein the injected link tracking codes can add identifiers at the application level as the association between messages when the messages are transmitted among nodes of the distributed application, and when a code injection method is called in the case execution process, the injected interceptor codes start the program collection of the distributed links and transmit the collected program codes to the data transmission module 3 by using asynchronous threads. The message transmission process between the abstract application nodes is a message input parameter, internal message processing logic and 3 parts of a return message, as shown in fig. 4, and the execution flow is shown in fig. 5.
The link call procedure of the distributed application injects enhancement code using bytecode enhancement techniques as follows for () logic and After () logic, as shown in fig. 6. The link tracing code can add an identifier at an application level as an association between messages when message passing occurs between nodes of the distributed application, so as to trace a call link process between applications and between nodes, and the tracing and identifying process is specifically shown in fig. 2.

step S101: the tester starts the distributed application system, and for a distributed application, each node to be started comprises a plurality of nodes.
Step S102: when the distributed system is started, the application probe modules of all the nodes are started together with the application by using the JVM tool interface.
After the application probe module is started, a request is sent to the control management module to acquire the distributed application unique identifier and the control switch information which are set in the control management module 1, and the information is refreshed into the memory.
Step S103: according to the distributed application unique identifier, the bytecode technology is utilized to modify the bytecode of the loaded program in the JVM in the application link information calling process, and specifically, the link tracking code is injected into the program.
Stage S20: and in the cross-application acquisition stage, a tester starts to execute a series of case operations, in the case execution process, a series of link calling programs in the distributed system are triggered, program acquisition codes in the injected interceptors run in the program calling process to start program acquisition, and the acquired codes are transmitted to a data sending module by using TCP/UDP + Thrift to prepare for being written into storage equipment. The method comprises the following specific steps:
step S201: a tester executes a specific case in the distributed application system, and distributed link calling is carried out among applications in the case execution process.
Step S202: after the distributed link call is triggered, since the link trace code is injected into the program (see fig. 6 for details), the execution of the injected link trace code is performed before the program is executed.
Step S203: the link tracking code collects and analyzes the link calling process and the call stack information of each distributed application according to fig. 2, distinguishes the calling relationship among the applications, and forms a completed link calling process. And transmitting the acquired data to the data transmission module by using an asynchronous data transmission thread in a TCP/UDP + Thrift mode.
Step S204: and transmitting the collected link calling process data to a data storage module in a data transmission module by adopting an asynchronous data transmission thread in a TCP/UDP + Thrift mode.
Step S30: and in the data storage stage, an asynchronous thread signal transmitted by the data transmission module is received, a data sending thread is informed, and sending data is written into the data storage module.
Step S301: and receiving an asynchronous thread signal of the data transmission module, notifying a data sending thread, and writing the asynchronous thread signal into the distributed data storage module in batches.
Step S302: the distributed data storage module can determine a medium for storing the collected programs according to the number of cases, and can store common databases or distributed files, and the data transmission mode is subject to requirements.
