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

JProfiler provides a lot of useful information on threading and monitor contention and it has an eclipse plugin.

See these screen casts for monitor contention analysis:

• Locking graphs in JProfiler
• Monitor events versus locking situations
• Cumulating and filtering monitor events
