The Space Utilization by Virtual Machine chart displays the amount of space used by the five virtual machines with the most space used on the datastore or the datastores in the cluster.
The Space Utilization by Virtual Machine chart is located in the Space view of the datastore Performance tab. The counter can also be displayed for datastore cluster charts.
|virtual_machine||Amount of datastore space used by the five virtual machines with the most used datastore space.
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 Client user interface. For information about consolidating the data center, see the vSphere documentation.
