statistics show-periodic

Continuously display current performance data at regular interval

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

Description

This command continuously displays specified performance data at a regular interval. The command output displays data in the following columns:
Note: This command has been deprecated and may be removed from a future version of Data ONTAP. Use the "statistics show" command with the tabular format instead.

Parameters

[-object <text>] - Object
Selects the object for which you want to display performance data. The default object is "cluster".
[-instance <text>] - Instance
Selects the instance for which you want to display performance data. This parameter is required if you specify the -object parameter and enter any object other than "cluster". Multiple values for this parameter are not supported.

For example, if you want to display disk object statistics, you can use this parameter to specify the name of a specific disk whose statistics you want to view.

[-counter <text>] - Counter
Selects the counters for which you want to display performance data. If you do not specify this parameter, the command displays statistics for all of the counters in the specified objects. To specify multiple counters, use "|" between each counter.
[-preset <text>] - Preset
If this parameter is specified, the command displays statistics for the specified preset.
[-node {<nodename>|local}] - Node
Selects the nodes for which you want to display performance data. The default node is "cluster:summary".
[-vserver <vserver name>] - Vserver
Selects the Vserver for which you want to display performance data. If you do not specify this parameter, the command displays statistics for all of the Vservers in the cluster.
[-interval <integer>] - Interval in Seconds
Specifies, in seconds, the interval between statistics updates. The default setting is 1 second.
[-iterations <integer>] - Number of Iterations
Specifies the number of iterations the command runs before terminating. The default setting is 0 (zero); this means that the command continues to run until you interrupt it by pressing Ctrl-C.
[-summary {true|false}] - Print Summary
Specifies whether the command prints a final summary of statistics after the command has gone through all of its iterations. The default setting is true.
[-filter <text>] - Filter Data
Selects instances that match the specified filter criteria. For example, to display instances from node1, specify -filter "node_name=node1".

Examples

The following example displays the "cluster" statistics for a node named node1. Because no number of iterations is specified, this command will continue to run until you interrupt it by pressing Ctrl-C.
