This is a set of munin plugins to monitor virtual machines managed via libvirt.
See INSTALL for installation instructions.
Setting things up
=================
Autoconfiguration is simple. Run:
munin-libvirt-plugins-detect
this will try to detect the hypervisor, create an apropriate configuration and
enable all plugins.
If you prefer to configure things by hand: The default uri used to connect to
libvirt is "qemu:///system". This can be changed in the plugin configuration:
cat <<EOF >/etc/munin/plugin-conf.d/libvirt
[libvirt-*]
env.uri xen:///
EOF
Enabling plugins by hand is the same as with any other munin plugin:
ln -s /usr/share/munin/plugins/libvirt-<plugin> /etc/munin/plugins/
/etc/init.d/munin-node restart
Plugin Configuration
====================
libvirt-mem and libvirt-cputime support [limits][] for critical and warning
values. These are set to 90% (warning) and 95% (critical) by default. However
you can change them in /etc/munin/munin.conf:
[somehost.example.com]
libvirt_cputime.total_pc.warning 60
libvirt_cputime.total_pc.critical 75
libvirt_mem.total_pc.warning 25
libvirt_mem.total_pc.critical 50
