Datastore counters
Table 1‑123. Data Counters
File Type Description
Virtual Disks Amount of disk space used by virtual disk les.
Virtual disk les store the contents of the virtual machine's hard disk drive, including information
that you write to a virtual machine's hard disk - the operating system, program les, and data
les. The les have the extension .vmdk and appear as a physical disk drive to a guest operating
system.
N Delta disks, which also have an extension .vmdk, are not included in this le type.

Swap Files Amount of disk space used by swap les.
Swap les back up the virtual machine's physical memory.

Snapshots Amount of disk space used by virtual machine snapshot les.
Snapshot les store information about virtual machine snapshots. They include snapshot state les
and delta disk les. A snapshot state le stores the running state of the virtual machine at the time
of the snapshot. It has the extension .vmsn. A delta disk le stores the updates made by the virtual
machine to the virtual disks after a snapshot is taken.

les.

Total Space Amount of disk space used by the virtual machine.
total space = virtual disk space + swap le space + snapshot space + other VM le space
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 les 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 les and removes the snapshots
from the vSphere Web Client user interface. For information about consolidating the data center, see the
vSphere documentation.
