Aggregate throughput and latency metrics

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

Description

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

  • Aggregate - aggregate name.

  • Node - node name.

  • Total Ops - total number of operations per second.

  • Read Ops - read operations per second.

  • Write Ops - write operations per second.

Parameters

[-aggregate <text>] - Aggregate

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

[-node {<nodename>|local}] - Node

Selects the node 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 maximum number of aggregates to display. The default setting is 25.

Examples

The following example displays aggregate statistics:

cluster1::> statistics aggregate show
cluster-1 : 12/31/1969 16:00:04

                                    *Total Read Write
