munin plugin for monitoring btrfs filesystems


This munin plugin uses the Python btrfs module to retrieve information about disk space allocation and usage.

Traditional space usage monitoring based on the output of df is not sufficient when using btrfs. This plugin takes allocated but unused disk space, and unallocatable disk space (for example when mixing different sized disks with raid profiles) into account. It is meant to be used as an addition to using a regular disk usage plugin, based on df output.
