What

The akwardly (re)named "graphite-munin" is a wrapper around Adam Jacob's "Munin-Node to Graphite bridge" candy
Basicaly, I just added an init script.

Target

This only been used in RHEL5.

Requirement

Your /etc/munin/munin-node.conf must contain

allow ^127\.0\.0\.1$
port 4949

Install

cd /opt
git clone https://github.com/kyzh/graphite-munin.git
cd graphite-munin
mv init.d/graphite-munin /etc/init.d

Configuration

Replace localhost by you graphite instance in both the init script and the ruby one. Replace it only at the top of the init script graphitehost=. Replace it only in the carbon class for the ruby script.
