vCenter only provides three CPU counters at cluster level (as shown in the next screenshot):
CPU Usage (MHz)
CPU Usage (Percent)
Total (MHz)
There is no storage or network metric group provided. Also, the data is not available in real time, meaning the data granularity is in intervals of 5 minutes, not 20 seconds.
Let us look at an example of the values of the 2 usage counters. I've excluded the Total metric in the next screenshot, as you would not be able to see the fluctuation in the Usage in MHz counter if I include it. The Total counter is a relatively static counter. It does not take into account HA. Changing the cluster setting does not impact this value. However, it does seem to take into account CPU power management. For example, I am getting a total value of 56 GHz whereas the actual total is 63 GHz. I check with a cluster with identical configuration (hardware and CPU power management) and the values differ slightly.
