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. It includes 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.

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

Other Amount of disk space used by all other non-virtual machine files, such as documentation files and backup
files.
Free Space Amount of disk space not currently in use.
Total Space Amount of disk space available to the datastore. It defines the datastore capacity. The chart displays the
information for datastores but not for data centers.
total space = virtual disk space + swap file space + snapshot space + other VM file space + other space +
free space
