Is there a way to extract snapshot delta information through OM?

[emanuel]

Hello all

I am curious if in operations manager if there is a graph version hiding somewhere that can show snap deltas from hourlys, nightlys, and weeklys ( ex: between hourly.0 and .1, weekly.1 and weekly.2 ) ?

or is there a way to grab the raw data and import it into an excel; like writing a custom report and dumping raw data?

No, there's not a graph. The problem is, if a volume has, say, 30 snapshots, for which two would we compute the delta?

There is a graph showing the long-term data overwrite rate (which, IIRC, computes snap delta between the oldest and most recent snapshots). Does that help?

Finally, from a volume details page, you can manually select two snapshots and compute the delta. I don't know if that's available from the CLI.

Its Volume Snapshot Details page that too when view at an individual volume level and not at filer/group levels.

 I don't know if that's available from the CLI.

You can use the dfpm dataset snapshot reclaimable cli.Its works for even for volumes which are not part of a dataset.

The only cavet is that you will need Provisioning Manager license.
