So you want to hack munin?

Sure. Things that needs to be done:

• POD document all plugins. This requires some knowledge about the system that is being graphed but little knowledge about programming.
• Look around the Wiki for things that needs to be documented better.
• Hang on the munin-users mailinglist being helpful.
• More AIX plugins
• More HP-UX plugins
• Plugins for different "engines": Java VMs (got that for basic JVM monitoring), JBoss, Java frameworks/APIs, Plone, Squid (got that), ...
• Make/improve (OO) plugin frameworks for Python, perl (Munin:OOPlugin ?), and Ruby?
• Solve [tickets/1 tickets]. Even if a ticket is taken there will probably be no-one working on it.
• Work on features, and consider the WishList. Note that some of the features also have tickets.
• Improve the munin exchange catalog

Ask on the munin-users mailing list if you have any questions.
