Answer

Unified Manager captures performance data every 5 minutes by retrieving ccma files that are generated on each node of a cluster. This is not real-time but based on one minute samples captured on the cluster.

 

You can navigate in Unified Manager to a particular volume and see the latency, iops, and throughput. You can also switch to the breakdown charts to get

further details such as read,write,other.

 

 

The closest equivalent via cli will be 'qos statistics volume performance show'
