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. VMware, Inc. 327
