How can I monitor how many threads and memory usage in my JVM or Eclipse?

Question

I want to monitor the memory usage and threading, how can I do on the Eclipse or JVM? Thanks.

Answer 1

in Eclipse, run the program in debug mode (this will also open the debug perspective). In that you can see how many threads are running. The best tool for this could be an inbuilt profiler . I guess JVM has a profiling tool as well or you can use third party profiling tool like JProfiler or yourkit. http://www.yourkit.com/
