Profiling HTTP calls and tracking them between JVMs
2022-09-22
Posted by Ingo Kegel
This screen cast shows how to profile HTTP calls with the HTTP client probe and use the HTTP remote request tracking feature to follow HTTP calls from one JVM into another.
A simple Spring Boot project with two application is profiled: A gateway server that serves static files and proxies API request to a second server that handles REST calls.
You can see how JProfiler tracks calls from the browser including the JavaScript stack trace through the gateway server into the REST server. The HTTP client probe with its various views is shown and its profiling settings are discussed.
