Hi,
I don't know how developers deal with profiling OpenNMS (the wiki was
bare) but I recently encountered some issues with OpenNMS going into a
deep CPU bound spin. I supply the following patch for comment, I only
chose TIJMP as it's packaged on Ubuntu. If there is a better open
source profiling tool I'm all ears.

Subject: [PATCH] Add support for the TIJMP profiler to the opennms
startup script
