show performance disk_domain

show performance disk_domain


The show performance disk_domain command is used to query the performance statistics on disk domains. If you want to analyze the real-time performance statistics on disk domains, run this command.


show performance disk_domain [ disk_domain_id=? ] [ disk_domain_id_list=? ]





disk_domain_id=? ID of the disk domain whose performance statistics you need to collect.

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

disk_domain_id_list=? ID list of disk domains whose performance statistics you need to collect.
  • To obtain the value, run "show disk_domain general".
  • Separate the IDs of disk domains with commas (,). Consecutive IDs can be represented by a hyphen (-).
  • A maximum of 50 IDs can be queried.



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 active performance statistics display.
  • "disk_domain_id" is mutually exclusive with "disk_domain_id_list".


Query the I/O throughput of disk domain "0".
