Monitor the disk usage of the minion
Specify thresholds for each disk and only emit a beacon if any of them are
exceeded.
.. code-block:: yaml
beacons:
diskusage:
- /: 63%
- /mnt/nfs: 50%
Windows drives must be quoted to avoid yaml syntax errors
.. code-block:: yaml
beacons:
diskusage:
- interval: 120
- 'c:\\': 90%
- 'd:\\': 50%
Regular expressions can be used as mount points.
.. code-block:: yaml
beacons:
diskusage:
- '^\/(?!home).*$': 90%
- '^[a-zA-Z]:\\$': 50%
The first one will match all mounted disks beginning with "/", except /home
The second one will match disks from A:\ to Z:\ on a Windows system
Note that if a regular expression are evaluated after static mount points,
which means that if a regular expression matches another defined mount point,
it will override the previously defined threshold.
