statistics namespace show

Namespace throughput and latency metrics

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


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


[-namespace <text>] - Namespace
Selects the Namespace for which you want to display performance data.
[-vserver <vserver name>] - Vserver
Selects the vserver 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 Namespaces to display. The default setting is 25.


The following example displays Namespace statistics:
cluster1::> statistics namespace show
cluster1 : 12/31/2017 16:00:04
