Snapshots can be used to monitor the disk usage of snapshots on a volume. Up until now, the check compared the sum of all snapshots on a volume to a threshold. The check is very flexible thanks to its various options, such as the possibility to compare in relation to the volume size.
The new switch ‑‑single can now be set to compare a particular snapshot with the threshold.
An example [A14] can be found on the help page of snapshots.
