Show volume performance statistics

The show volume performanceStats command returns information about volume performance.

Supported Arrays

This command applies to any individual storage array, including the E2700, E5600, E2800, E5700, EF600 and EF300 arrays, as long as all SMcli packages are installed.

Roles

To execute this command on an E2800, E5700, EF600, or EF300 storage array, you must have the Storage Admin or Storage Monitor role.

Context

For each volume in the storage array, this command returns the following information:

Syntax

show (allVolumes | volume ["volumeName"] 
volumes ["volumeName1" ... "volumeNameN"]) performanceStats

Parameters

Parameter Description
allVolumes The parameter to return performance statistics about all of the volumes in the storage array.
volume

The name of a volume for which you want to retrieve information. Enclose the volume name in square brackets ([ ]). If the volume name has special characters or numbers, you must enclose the name in double quotation marks (" ") inside square brackets.

volumes

The names of several volumes for which you want to retrieve information. Enter the names of the volumes using these rules:

  • Enclose all of the names in square brackets ([ ]).
  • Separate each of the names with a space.

If the volume names have special characters or numbers, enter the names using these rules:

  • Enclose each of the names in double quotation marks (" ").
  • Separate each of the names with a space.

Notes

Before you run the show volume performanceStat command, run the set session performanceMonitorInterval command and the set session performanceMonitorIterations command to define how often you collect the statistics.

The show volume performanceStat command returns volume performance statistics as shown in this example:
