Top volumes on aggregate

r2401 — Wed, 21 Aug 2019 15:38:45 GMT

Hello All,

I have been trying to see if there is a way to get TOP IO volumes for specific aggregate via CLI without perfstat. Looking at the link it appears its possible. Not sure if we need to enable something for this. Its failing currently with error counter does not exist. Checking if any one where able to get this.

https://docs.netapp.com/ontap-9/index.jsp?topic=%2Fcom.netapp.doc.dot-cm-cmpr-910%2FTOC__statistics__volume.html&lang=en

This is on 9.1

statistics vol show -aggregate aggr1

Error: command failed: Filter data contains a counter that does not exist:

"parent_aggr".

How about a REST API call to OCUM?

Looks like we will need to setup another server to use the REST API's. If I have more requests that will need API's I can justify the use of another server to business.

going back to CLI method. I see the documentation shows the aggregate field but when the command is run it gives error.

That error is seen from 'admin' & 'advanced' privilege level.

From 'diag' it works.
