Data ONTAP 8.2 Reference - qos statistics workload resource disk show

qos statistics workload resource disk show

Display disk resource utilization data per QoS workload

Availability: This command is available to cluster administrators at the admin privilege level.

Description

The qos statistics workload resource disk show command displays the disk utilization for QoS workloads per node. The disk utilization shows the percentage of time spent on the disk during read and write operations. The command displays disk utilization for system-defined workloads; however, their disk utilization is not included in the total utilization.

The command displays the following data:

The QoS workload name (Workload)
The QoS workload ID (ID)
Disk utilization (Disk)
The number of data disks utilized (No. of Disks)

The results displayed are sorted by total disk utilization. Each iteration starts with a row that displays the total disk utilization across all QoS workloads.

Parameters

-node {<nodename>|local} - Node

Selects the QOS workloads that match this parameter value.

[-iterations <integer>] - Number of Iterations

Specifies the number of times the display is refreshed before terminating. If you do not specify this parameter, the command iterates until interrupted by Ctrl-C.

[-rows <integer>] - Number of Rows in the Output

Specifies the number of busiest QoS workloads to display. The default setting is 10. The allowed range of values is 1 to 20.

[-refresh-display {true|false}] - Toggle Screen Refresh Between Each Iteration

Specifies the display style. If true, the command clears the display after each data iteration. If false, the command displays each data iteration below the previous one. The default is false.

Examples

            cluster1::> qos statistics workload resource disk show -node nodeB -iterations 100 -rows 3
            Workload          ID   Disk  No. of Disks
            --------------- ------ ----- ------------
            -total- (100%)       -   30%            4
            _RAID                -   20%            4
            vs0-wid101         101   12%            2
            file-1-wid121      121   10%            1
            vol0-wid1002      1002    8%            1
            _WAFL                -    7%            3
            -total- (100%)       -   30%            4
            vs0-wid101         101   12%            2
            file-1-wid121      121   10%            1
            _RAID                -   10%            4
            vol0-wid1002      1002    8%            1
            _WAFL                -    7%            3

The example above displays total disk utilization for the 3 QoS workloads with the highest disk utilization and it refreshes the display 100 times before terminating.
