Yep, the wiki is here: http://wiki.apache.org/hadoop/HowToUseJCarder
Thanks. I was hoping for a simpler process/script to reproduce these graphs though I agree with you on the wiki that it's important to avoid false positives to reduce noise. These two cycles are already borderline and practically harmless, as unlike start/stop, init/shutdown doesn't overlap registration.
I'm working on getting access to the new build infrastructure so I can set up hudson jobs to run jcarder on a regular basis
This will be a time saver. +1 and Thanks!
