The actual selections available in this area change depending on the type of object that you
have selected within the vCenter Web Client. That is, the options available when viewing the
Monitor
➢
Performance tab for an ESXi host are different from the options available when view-
ing the Monitor
➢
Performance tab of a VM, a cluster, or a datacenter.
Within each of these resources, different objects and counters are available. Be aware that other
factors affect what objects and counters are available to view; for example, in some cases the real-
time interval shows more objects and counters than other intervals. A description i eld within
the counters list explains what each counter represents. If this description does not i t within the
Chart Options dialog box, simply mouse over it to view the full text. The next few sections list
the various counters that are available for the different resource types in the Chart Options
dialog box.
Viewing CPU Performance Information
If you select the CPU resource type in the Chart Options dialog box, you can choose what
specii c objects and counters you'd like to see in the performance chart. Note that the CPU
resource type is not available when viewing the Performance tab of a datacenter object (DC).
It is available for clusters (CL), ESXi hosts (ESXi), resource pools (RP), and individual virtual
machines (VM).
Table 13.2 lists the most important objects and counters available for CPU performance infor-
mation. A complete list of all CPU performance counters can be found at
