check_netapp_pro already provides a way to flag volumes which do not have snapshots at all. The check SnapshotLessVolume just looks for the size used by snapshots and if that size is equal to 0 it will raise an alarm.
Lately, while working on a check for snapmirrors, I found some attributes from which we could derive and check the snapshots policy name and the number of snapshot copies in the volume.
Are you interested?
So my question is: Would it make sense for some of our customers to check for:
- a given snapshot-policy name
and/ or
- the number of snapshots on the volume additionally to the already provided check for the size taken by snapshots?
Examples
Here are a couple of examples of how this check might look like once we’ve implemented it:
check_netapp_pro SnapshotPolicy -H <filer> --name=SalesDepartment
Check all volumes snapshot-policy and raise an alarm if their name does not equal SalesDepartment.
check_netapp_pro SnapshotPolicy -H <filer> -w 7 -c 3
Check all volumes snapshot-policy and raise a warning, if less than 7 copies are available (and a critical alarm if less than 3).
Please feel free to get in touch with us if you would like to see this check implemented in one of the next releases.
