Beacon to monitor disk usage.
New in version 2015.5.0.
python-psutil
Monitor the disk usage of the minion
Specify thresholds for each disk and only emit a beacon if any of them are exceeded.
beacons:
  diskusage:
    - /: 63%
    - /mnt/nfs: 50%
Windows drives must be quoted to avoid yaml syntax errors
beacons:
  diskusage:
    -  interval: 120
    - 'c:\\': 90%
    - 'd:\\': 50%
Regular expressions can be used as mount points.
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.
