#### btrfs <a id="plugins-contrib-command-btrfs"></a>
The [btrfs plugin](https://github.com/knorrie/python-btrfs/)
is used to check the btrfs storage health on the server.
The plugin requires `sudo` permissions.
You can add a sudoers file to allow your monitoring user to use the plugin, i.e. edit /etc/sudoers.d/icinga and add:
```
icinga ALL=(root) NOPASSWD:/usr/lib/nagios/plugins/check_btrfs
```
and set the correct permissions:
```bash
chown -c root: /etc/sudoers.d/icinga
chmod -c 0440 /etc/sudoers.d/icinga
```
[monitoring-plugins-btrfs](https://packages.debian.org/monitoring-plugins-btrfs) provide the necessary binary on debian/ubuntu.
Custom attributes passed as [command parameters](03-monitoring-basics.md#command-passing-parameters):
Name | Description

btrfs_awg | **Optional.** Exit with WARNING status if less than the specified amount of disk space (in GiB) is unallocated
btrfs_acg | **Optional.** Exit with CRITICAL status if less than the specified amount of disk space (in GiB) is unallocated
btrfs_awp | **Optional.** Exit with WARNING status if more than the specified percent of disk space is allocated
btrfs_acp | **Optional.** Exit with CRITICAL status if more than the specified percent of disk space is allocated
