Display KHI Performance Information

Use the following commands to display KHI information about the performance of the switch.

Procedure

  1. To enter User EXEC mode, log on to the switch.
  2. Display buffer performance and utilization statistics:

    show khi performance buffer-pool [{slot[-slot][,...]}]

  3. Show current utilization, 5-minute average utilization, and 5-minute high water mark with date and time of event:

    show khi performance cpu [{slot[-slot][,...]}]

  4. Display memory performance and utilization statistics on the specified slot or all slots:

    show khi performance memory [history | {slot[-slot][,...]}]

    Note

    Note

    Depending on the hardware platform, you can display virtual memory history.

  5. Display process performance and utilization statistics on the specified slot or all slots:

    show khi performance process [{slot[-slot][,...]}]

  6. Display thread performance and utilization statistics on the specified slot or all slots:

    show khi performance pthread [{slot[-slot][,...]}]

  7. Display the queue performance and utilization statistics on the switch:

    show khi performance rx-queue

  8. Display internal memory management resource performance and utilization statistics on the specified slot or all slots:

    show khi performance slabinfo [{slot[-slot][,...]}]
