Tomcat memory profilers

Question

Can someone suggest a good tomcat memory profiler? (I am trying to profile the memory usage of a JRuby on Rails app deployed on a Tomcat instance in a Windows machine).

Answer 1

You can use VisualVM which is part of the JDK - more recent versions can be downloaded from visualvm.java.net/.

Or you can use the integrated profiler from NetBeans which is essentially the same thing as VisualVM just with some additional features.
