[jboss-user] [Performance Tuning] - JMX Snapshot ?

[kejoseph]

Hi -

When a JBoss JVM hangs, is it possible to obtain a JMX "snapshot" of the system for troubleshooting later ? I wrote some twiddle scripts to get various JMX values, but the script returns errors as the JVM is not responsive at that point.

I have taken thread dumps (using kill -3), but they are not very useful. Just wondering whether there is some way (like kill -3) to take a snapshot as well.

Thanks,
-Kevin.
