show performance disk

show performance disk

Function

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

Format

show performance disk [ disk_id=? ] [ disk_id_list=? ]

Parameters

Parameter

Description

Value

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

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

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

Level

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.

Example

Query the I/O throughput of the disk in slot "0" of enclosure "CTE0.0".
