show performance nfsv4

show performance nfsv4

Function

The show performance nfsv4 command is used to query the performance statistics for NFSv4. Run this command to analyze the performance statistics for NFSv4 in real time.

Format

show performance nfsv4 controller_id=?

show performance nfsv4 controller_id_list=?

Parameters

Parameter

Description

Value

controller_id=?

ID of a controller.

Use the command "show controller general" to get the value.

controller_id_list=?

ID list of controllers.

  • Use the command "show controller general" to get the value.
  • Separate the controller IDs with commas (,), such as "0A,1B".

Level

Guest

Usage Guidelines

  • You will be prompted with optional performance statistics categories upon running this command. In this condition, typing a number or multiple numbers (separated by commas) for the selected categories and pressing "Enter" displays the performance statistics for those categories.
  • 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 NFSv4 performance statistics of controller "1A".
