I don't know how many people out there are using Munin[1] for monitoring, but I wrote a few simple plugins[2] today as I couldn't find others after a quick search.
They just require Perl (obviously, it's Munin), LWP::UserAgent, and JSON, and all use the _stats endpoint. I haven't done much extensive testing beyond graphing for a couple hours on my very low-load box. If somebody has done Munin plugins already (and probably done a far better job) I'm definitely interested :) [1] http://munin.projects.linpro.no/ [2] http://github.com/strattg/munin-plugin-couchdb/tree/master
