Viewing Datastore Performance Information
Monitoring datastore performance allows you to see the performance of the whole datastore
instead of using disk counters per VM. Datastore performance counters are available only for
ESXi hosts and VMs; they are not available for datacenter objects, clusters, or resource pools.
Table 13.7 shows the most important objects and counters available for datastore performance
information. A complete list of all datastore performance counters can be found at
