qos statistics workload latency show

Display latency breakdown data per QoS workload

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

Description

The qos statistics workload latency show command displays the average latencies for QoS workloads on Data ONTAP subsystems.

The command displays the following data:

The results displayed per iteration are sorted by the total latency field. Each iteration starts with a row that displays the average latency, in microseconds (us) or milliseconds (ms) observed across all QoS workloads.

Parameters

[-node {<nodename>|local}] - Node
Selects the QOS workloads that match this parameter value. If you do not specify this parameter, the command displays data for the entire cluster.
[-iterations <integer>] - Number of Iterations
Specifies the number of times that the command refreshes the display with updated data before terminating. If you do not specify this parameter, the command continues to run until you interrupt it by pressing Ctrl-C.
[-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.
{ [-rows <integer>] - Number of Rows in the Output
Specifies the number of busiest QoS policy groups to display. Valid values are from 1 to 20. The default value is 10.
[-policy-group <text>] - QoS Policy Group Name
Selects the QoS workloads that belong to the QoS policy group specified by this parameter value. If you do not specify this parameter, the command displays data for all QoS workloads.
| [-workload <text>] - QoS Workload Name
Selects the QoS workload that match this parameter value. If you do not specify this parameter, the command displays data for all QoS workloads.
| [-workload-id <integer>]} - QoS Workload ID
Selects the QoS workload that match the QoS workload ID specified by this parameter value.
[-show-flexgroup-as-constituents {true|false}] - Display Flexgroups as Constituents
If the parameter is specified and if the value is true, it will display data for FlexVols and Flexgroup Constituents. Otherwise it will display data for FlexVols and Flexgroups.
