QoS workload throughput and latency metrics

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

Description

This command continuously displays performance data for workloads at a regular interval. The command output displays data in the following columns:

  • Workload - workload name.

  • Total Ops - total number of operations per second.

  • Read Ops - read operations per second.

  • Write Ops - write operations per second.

  • Other Ops - other operations per second.

  • Read (Bps) - read throughput in bytes per second.

  • Write (Bps) - write throughput in bytes per second.

  • Latency(us) - average latency for an operation in microseconds.

Parameters

[-workload <text>] - Workload (privilege: advanced)

Selects the workload for which you want to display performance data.

[-sort-key <text>] - Column to Sort By (privilege: advanced)

If this parameter is specified, the command displays statistics sorted by the specified column.

-interval <integer> - Interval (privilege: advanced)

Specifies, in seconds, the interval between statistics updates. The default setting is 5 seconds.

-iterations <integer> - Iterations (privilege: advanced)

Specifies the number of iterations the command runs before terminating. The default setting is 1. If the number is 0 (zero), the command continues to run until you interrupt it by pressing Ctrl-C.

-max <integer> - Maximum Number of Instances (privilege: advanced)

Specifies the maximum number of workloads to display. The default setting is 25.

Examples

The following example displays workload statistics:

cluster1::> statistics workload show
cluster1 : 12/31/2013 16:00:04
