show performance elink

show performance elink


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


show performance elink { link_id=? | link_id_list=? }





link_id=? ID of the heterogeneous link whose performance statistics you need to collect.

To obtain the value, run the "show remote_device elink" command.

link_id_list=? ID list of heterogeneous links whose performance statistics you need to collect.
  • To obtain the value, run the "show remote_device elink" command.
  • Separate the IDs of heterogeneous links with commas (,). Consecutive IDs can be represented by a hyphen (-). Only the same type (such as Fibre Channel or iSCSI) of heterogeneous links are supported. A maximum of 2048 links can be displayed.



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.
