Table 1‑30. Data Counters
Chart Label Description
<datastore> Amount of provisioned storage space on the top 10 datastores with the most provisioned
space.

Counter: provisioned

Stats Type: Absolute

Unit: KiloBytes (KB)

Rollup Type: Latest

Collection Level: 1
Chart Analysis
The datastore is at full capacity when the used space is equal to the capacity. Allocated space can be
larger than datastore capacity, for example, when you have snapshots and thin-provisioned disks. If
possible, you can provision more space to the datastore, or you can add disks to the datastore or use
shared datastores.
If snapshot files are consuming high datastore space, consider consolidating them to the virtual disk when
they are no longer needed. Consolidating the snapshots deletes the redo log files and removes the
snapshots from the vSphere Web Client user interface. For information about consolidating the data
center, see the vSphere documentation.
Space Capacity by Datastore in GB
The Space capacity by Datastore in GB displays the top 10 configured size of the datastores in the
datastore cluster.
This chart is located in the Space view of the Datacenter Performance tab.
