statistics node show

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       -
