Disk/CSV: Write Latency

Millisecond

Average latency between the time a write request arrived to the file system and the time when it was completed.

Disk/CSV: Latency

Millisecond

Average latency required to complete read and write operations on a volume.

Datastore Queue Length

Disk/CSV: Read Queue Length

Number

Number of read operations queued for a volume.

Disk/CSV: Write Queue Length
