show performance smartqos_policy

show performance smartqos_policy


The show performance smartqos_policy command is used to query the performance statistics on SmartQoS policies.


show performance smartqos_policy smartqos_policy_id=?

show performance smartqos_policy smartqos_policy_id_list=?






ID of the SmartQoS policy whose performance statistics you need to collect.

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


ID list of SmartQoS policies whose performance statistics you need to collect.

  • To obtain the value, run "show smartqos_policy general".
  • Multiple IDs are separated by commas (,). 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, or enter consecutive serial numbers and separate them with hyphens (-).
  • Performance statistics will be updated in real time.
  • Typing "q" on the command line interface (CLI) exits the active performance statistics display.


Query the I/O throughput of SmartQoS policy "0".
