show performance controller

show performance controller

Function

The show performance controller command is used to query the performance statistics on a controller of the storage system. Run this command to analyze the performance statistics on a controller in real time.

Format

show performance controller controller_id=? [ mode=? ] [ times=? ]

show performance controller controller_id_list=? [ mode=? ] [ times=? ]

Parameters

Parameter

Description

Value

controller_id=?

ID of a controller.

To obtain the value, run "show controller general".

controller_id_list=?

ID list of controllers.

  • To obtain the value, run "show controller general".
  • Separate the controller IDs with commas (,).

mode=?

Mode name.

To obtain the value, run the "show performance mode" command.

times=?

Display times.

The value must be an integer from 1 to 65535.

Level

Guest

Usage Guidelines

  • You need to specify the controllers whose statistics you want to query.
  • If parameter "times" is not specified, the performance data will be refreshed in real time until you press q to exit. If parameter "times" is specified, the performance data is refreshed for the specified times and then the system automatically exits the performance data query.
  • If parameter "mode" is not specified, performance data categories are displayed after this command is executed. You can enter the serial number before a category and press "Enter" to view the category of data. You can enter multiple serial numbers and use commas (,) to separate them.
  • If parameter "mode" is specified, performance data in the specified mode will be refreshed in real time. You can run the "show performance mode mode=?" command to view performance data categories.

Example

  • Query the performance statistics on the read I/Os of controller "0A".
