Tracing/Profiling applications on tomcat

Question

I have been trying to find some opensource component to trace(call stack/method call stack)/profile applications on tomcat.

I have tried to look at options like Eclipse Diver, JIVE for eclipse and javacalltracer, java melody, psi probe.

These options do not seem to be capable of accomplishing the goals:

1. view call trace, sequence of calls (including filters, listeners, Tomcat classes and my web application classes).

2. provide time breakups for calls/memory analysis for components.

I am trying to find something that is inline with the features provided by JProfiler.

Is there any tool/open source projects that might provide similar functionality?

My system info:

Windows 7 enterprise 64bit.

Tomcat 6.0.20

JDK 6

Multiple web applications (about 10) with spring and ibatis.

Answer 1

I strongly recommend BTrace. It allows you to trace/inspect/etc far beyond the things you've mentioned. And it's free.
