Checks the number of snapshots that match one or more filter criteria.
This plugin counts the number of snapshots, which have a defined age (or match other filter-criterias).
--younger-than / --older-than: Sets age limits to ensure that only recent snapshot copies are counted or to warn against snapshot copies that are too old. See Durations.
--include / --exclude: Filter based on the instance names.
$ check_netapp_snapshot volume count -H filer --warning=7 --critical=2 --comparison=lt
Checks all snapshots on all volumes on all aggregates. Returns CRITICAL if at least one of the volumes has less than 2 snapshot-copies (or warning if less than 7).
$ check_netapp_snapshot volume count -H filer --warning=7 --critical=2 --comparison=lt --younger-than=10d
Same as above, but count only snapshot-copies created within the last 10 days.
$ check_netapp_snapshot volume count -H filer --warning=5 --critical=10 --comparison=gt --older-than=52w
Check for Snapshot copies that are too old (orphaned). Returns CRITICAL if there are more than 10 Snapshot copies, each of which is older than 1 year.
