How to take a thread dump

Yesterday, I was looking to find whether any daemon thread is running with in jboss server, which does an scheduled job.

Tried ps -efw but it didn't worked, as it's an internal thread, got some suggestions that dumpingthe jboss process will dump the name of daemon threaad and finally it worked great :)


# Find the running boss server process id.

ps -efww | grep 'java' #choose your jboss server pid.

# send thread dump signal.
kill -3 $pid
