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. You can
provision more space to the datastore if possible, or you can add disks to the datastore or use shared
datastores.
If snapshot files are consuming a lot of 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 Utilization By File Type
The Space Utilization By File Type chart displays datastore space usage for virtual disks, swap files,
snapshot files, and other virtual machine files.
NOTE This chart does not show historical statistics. It only shows the most recently available data, which
may be up to 30 minutes late, depending on when the last statistics rollup occurred. In addition, statistics
are not collected across all datastores at one time. They are collected asynchronously.
The Space Utilization by File Type chart is located in the Storage view of the data center Performance tab.
Datastore Counters
Table 1‑25. Data Counters
File Type Description
Virtual Disks Amount of disk space used by virtual disk files.
Virtual disk files store the contents of the virtual machine's hard disk drive, including information
that you write to a virtual machine's hard disk, such as the operating system, program files, and
data files. The files have the extension .vmdk and appear as a physical disk drive to a guest
operating system.
NOTE Delta disks, which also have an extension .vmdk, are not included in this file type.
