System utilization metrics for each node in the cluster

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

Description

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

  • Node - node name.

  • CPU (%) - CPU utilization.

  • Total Ops - total number of operations per second.

  • Latency(ms) - average latency for an operation in milliseconds.

Parameters

[-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 the maximum number of aggregates to display. The default setting is 25.

Examples

The following example displays node statistics:

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

       CPU *Total Latency
  Node (%)    Ops    (ms)
 ----- --- ------ -------
 node2  76    113       -
 node1  58     10       -
