Snapshots history and specific alarms for objects

jcbettinelli — Thu, 05 Jun 2025 05:59:57 GMT

Hello,

One of my customer is running a MetroCluster, and he's having some questions, which I haven't find answers yet.

- Is it possible to get the history of snapshots with their sizes for a specific volume or aggregate?

- Can we setup an alarm different than the threshold for a specific volume?

Thank you in advance,

Jean-Christophe

Hi Jean,

Pls find my responses inline.

- Is it possible to get the history of snapshots with their sizes for a specific volume or aggregate?

Did you try the snapshot reports ? Can you give me some example of what you are looking for ? So that I can tell you if that is possible with OCUM or not.

- Can we setup an alarm different than the threshold for a specific volume?

By alarm you mean alarm for the snapshot usaage ? If so yes we already have one.

[root@vmlnx ~]# dfm options list | grep -i volsnap

volSnapshotCountThreshold 250

volSnapshotFullThreshold 90

volSnapshotTooOldThreshold 52 weeks

[root@vmlnx ~]# dfm eventtype list | grep -i df.snapshot.kbytes

snapshot-full Warning df.snapshot.kbytes

snapshot-space-ok Normal df.snapshot.kbytes

[root@vmlnx ~]# dfm eventtype list | grep -i old-snap

snapshots:not-too-old Normal old-snaps

snapshots:too-old Warning old-snaps

[root@vmlnx~]#

Hello Adai,

I hope you enjoyed your visit to Switzerland

I haven't try the snapshot reports, I'm going to have a look on this.

Regarding the alarms, I'm looking for space usage specific for volumes.

Because the percentage is not always valuable for volumes or aggregate for different sizes (from GB to TB).

Thank you in advance,

Jean-Christophe

Hi Jean-Christophe,

Yup pretty much, but it was warm when I landed and became hot when I was about to leave. I did try Fondue and liked it.

BTW though you can set different percentage value for each volumes snapshot usage, but unfortunately its still percentage.

Also the percentage is of the SnapReserve and not the full volume capacity.
