show performance controller

show performance controller


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.


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

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





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.



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, the system will prompt you to enter the serial numbers of performance data types and press Enter to view data of specified types. Use commas (,) to separate multiple serial numbers. Performance data of the specified types will be refreshed in real time.
  • If parameter node 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 types.).


  • To query the performance statistics on the read I/Os for controller "0A", run the following command.

    admin:/>show performance controller controller_id=0A
