Munin Plugin for Varnish 4

Modified version of the plugin for Varnish 2/3 from the munin distribution to adapt to the XML output of Varnish 4 varnishstat.

Installation

  • Copy varnish4_ to the Munin plugins directory (/usr/share/munin/plugins/)
  • Make varnish4_ runnable (chmod +x /usr/share/munin/plugins/varnish4_)

Configuration

Run munin-node-configure --shell and link the aspects to monitor to your actual plugins directory.

In your plugins.conf add

[varnish4_*]
     group varnish
     env.varnishstat varnishstat
     env.name

group varnish Since Varnish version 4.1, Varnish shared log utilities must be run in a context with varnish group membership.

env.varnishstat can be a full path to varnishstat if it's not in the path already.

env.name is blank (undefined) by default and can be used to specify a -n name argument to varnish if multiple instances are running on the same server.
