Tracing Sites Requests in Using Web Applications

Quite often, developers face low performance, hanging, and other problems when they’re developing sites. To solve such problems, we need to trace site requests. Existing tracing methods do not allow tracing the progress of requests from a client’s web browser to a server or group of servers. In this paper, we propose distributed tracing mechanism that allows tracking requests starting from the browser. For generating complete client-to-server tracing, the client application must be able to initiate the appropriate request. For the execution of these actions, we need to use a unique library. In the paper, we consider the algorithm of such a library. A popular tracer (OpenTracing) is used on the serverside. Based on the proposed methodology, a library was developed. The library's work was tested. Testing has shown that using the library, and we can track the complete chain of requests from a browser to the server. Trace result is presented in graphical view. This allows analyzing received data and finding bottlenecks when queries are passing. The novelty of the proposed solution is that the request is traced from the client application and to the client application. That is, the full path of the request is shown. The result is presented in a graphical form that is convenient for analysis. The library is designed primarily for the development of client-server applications and for support services.
