These plugins are originally taken from muninexchange to have a git repository to check out on every munin node
on your munin node do:
cd /usr/share/munin/plugins (or your munin plugins directory)
sudo git clone git://github.com/basiszwo/munin-varnish.git
sudo chmod a+x /usr/share/munin/plugins/munin-varnish/varnish_*
sudo ln -s /usr/share/munin/plugins/munin-varnish/varnish_* /etc/munin/plugins/
change your munin node config and add the following to /etc/munin/plugin-conf.d/munin-node
[varnish*]
user root
restart your munin node:
sudo /etc/init.d/munin-node restart
This munin plugin for Varnish 2.x has been removed from the varnish repostory. You may find it in the official munin repository
As it was a bit tricky to get this plugin running I want to share my experiences with it.
on your munin node do:
cd /usr/share/munin/plugins (or your munin plugins directory)
sudo git clone git://github.com/basiszwo/munin-varnish.git
sudo chmod a+x /usr/share/munin/plugins/munin-varnish/varnish2_
Depending on what you want to monitor link the varnish2_ script to one of the following:
hit_rate, request_rate, objects, backend_traffic, transfer_rates, threads, memory_usage, uptime, vcl_and_purges, expunge, vcl_and_purges, lru, allocations, shm, shm_writes, session, session_herd, objoverflow, esi, hcb, obj_sendfile_vs_write, losthdr, objects_per_objhead
