  • statistics workload show

    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

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

    [-sort-key <text>] - Column to Sort By

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

    -interval <integer> - Interval

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

    -iterations <integer> - Iterations

    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

    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
