Profiling Netapp

Hello colleagues,

I have a customer with 12 Netapp clusters.
How exactly must the measurement be performed here?

Must all nodes in a cluster be measured individually, or are all nodes in a cluster measured together?
If we then have 12 measurements, can we combine them?
And we can only measure 1 cluster, not several simultaneously?
This would mean that the customer would have to start Live Optics from 12 different measuring stations.
So how does this work with the time offset?

Regards

Marc
