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. If you need to analyze the real-time performance statistics on a controller, run this command.


show performance controller controller_id=?

show performance controller controller_id_list=?





controller_id=? Controller ID.

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 (,).



Usage Guidelines

  • After this command is executed, performance data categories are displayed. 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.
  • Performance statistics will be updated in real time.
  • Typing "q" on the command line interface (CLI) exits the performance statistics display.


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