I am looking for an open-source application/tool/technology which can show times of distributed request across distributed system.
I have found some wonderful stuff like AppDynamics, but they are all commercial. I don’t need such a wide functionality, but simple request tracking. I have also had a look on this list, but I have some difficulties to understand it.
Could you recommend some solutions if you are experienced with APM?
i don’t think that you can do full-featured profiling of distributed request across number of JVM’s – AppDynamics from what i can remember understands the EE stuff – like calling DB, EJB, RMI, or remote webservice – however it still works in scope of JVM.
Isn’t it suffient in your case just to use java profiler (like yourkit, jprofiler)?
