    Disk/CSV: Queue Length

    Number

    Number of read and write operations that were queued for a volume during the sample interval.

    Direct/Redirected Usage

    Disk/CSV: Redirected Bytes/sec

    KB/s

    Average amount of data transferred to or from a disk during write or read operations over the network stack.

    Disk/CSV: Direct Bytes/sec

    KB/s

    Average amount of data transferred to or from a disk during write or read operations.

    Direct/Redirected Latency

    Direct/Redirected IOPS

    Disk/CSV: Direct IOPS

    Number

    Rate at which read and write operations were performed directly on a disk.

    Disk/CSV: Redirected IOPS

    Number

    Rate at which read and write operations were redirected to a volume through the network.
