Is there a way to check the code injected by the java agent?

Is there a way to check that the java agent is correctly instrumenting the application (without running it and use a visualization tool like Jager UI)

hi @SimoneGiusso! do you mean something like this? https://github.com/open-telemetry/opentelemetry-java-examples/tree/main/telemetry-testing

I would be curios about the possibility to look at the code added by the agent, but I'm not sure if it possible since the code is added at runtime.

Add -Dnet.bytebuddy.dump=/some/dir to jvm arguments and run your application. Classes transformed by byte buddy should end up in the specified directory. Disassemble these classes with javap or whatever you like to examine what the agent added.
