CPU Metrics
The cpu metric group tracks CPU utilization for hosts, virtual machines, resource pools, and compute
resources.
Table C-2 lists the CPU data counters.
NOTE The performance charts display a subset of the CPU data counters. The entire set is collected and available
in vCenter Server. You can use the vSphere Web Services SDK to query vCenter Server and get statistics for
those counters. For more information, see the VMware vSphere API Reference.
