Those are good if you want to know more about _why_ your utilization metric is high, but looking at them on their own is only part of the story. Nothing you see by looking at the domains is going to help you _more_ than just monitoring utilization, because utilization _includes_ the only domain that could cause you pain by being over utilized.

Don’t know if we’re allowed to attach images, but I’ll try. If you can see the attached image, you see that marrying OCPM -> NetApp Harvest -> Grafana you get a really nice breakdown of these processes.
Sadly no alerting, just monitoring.

utilization is supposed to include CPU load, kahuna load and disk busy % as factors in it¹s value.
In theory, it should make a better metric for node utilization than just CPU cores by themselves. While I recognize that is not really helpful if you are trying to do a deep dive into Œwhy¹ things are happening on a given node, OPM is supposed to make it easy for you to alarm on Œperformance of node is going¹, without having to do if cpu > x and kahuna y and disk busy > z then page me that the controller is melting.

Hi Steve,
I ended up having to follow NetApp¹s instructions on sending OCPM data to Graphite (and later Grafana via the NetApp harvest toolbox tool), then graphing the individual CPU counters. OCPM just tracks ³utilization² of the node, which is just not helpful.

In former versions of DFM or whatever it was called now, I was able to chart individual CPU¹s in Performance Manager. Now, I only see an average across all processors w/ 2.x OnCommand Performance Manager. I know I can drop down to the console, and run a sysstat -whatever... but was wondering if I was missing something for OnCommand Performance Manager to see, or graph individual CPUs. Is this an option, or how would I enable, setup? I am running the LOD, and can't see how this can be done... If its not available, that was of value to some of my customers.
