Viewing Storage Path Performance Information
Storage Path is one of the new categories of performance counters. As the name suggests, these
counters can help you troubleshoot storage path problems. Storage path counters are available
only for ESXi; they are not available for datacenter objects, clusters, VMs, or resource pools.
Table 13.8 shows the objects and counters available for storage path performance information.

Viewing Other Performance Counters
The following performance counter types are also available:
ESXi hosts participating in a cluster also have a resource type of Cluster Services, with two
performance counters: CPU Fairness and Memory Fairness. Both of these counters show
the distribution of resources within a cluster.
◆
The datacenter object contains a resource type marked as Virtual Machine Operations.
This resource type contains performance counters that simply monitor the number of
times a particular VM operation has occurred. These include VM Power-On Events, VM
Power-Off Events, VM Resets, vMotion Operations, and Storage vMotion Operations.
