Parameters
job job-id: Specifies a process by its ID. If no process is specified, this command displays the historical
CPU usage statistics for the entire system, which is the sum of the historical CPU usage statistics for all
processes in the system. To view the IDs and names of the running processes, use the display process
command. For more information, see Network Management and Monitoring Configuration Guide.
slot slot-number: Specifies a card by the number of the slot where the card resides. If no card is specified,
this command displays the historical CPU usage statistics for the active MPU. (In standalone mode.)
chassis chassis-number slot slot-number: Specifies a card on an IRF member device. The chassis-number
argument refers to the ID of the IRF member device, and the slot-number argument refers to the number
of the slot where the card resides. If no IRF member device or card is specified, this command displays
the historical CPU usage statistics for all cards in the IRF fabric. (In IRF mode.)
cpu cpu-number: Displays the historical CPU usage statistics for the specified CPU. If this option is not
provided, the command displays the historical CPU usage statistics for all CPUs on the card in the
specified slot.
Usage guidelines
The system regularly collects CPU usage statistics and saves the statistics in the history record area. This
command displays the CPU usage statistics for the last 60 minutes in axes as follows:
• The vertical axis represents the CPU usage. If a statistic is not a multiple of the usage step, it is
rounded up or down to the closest multiple of the usage step, whichever is closer. For example, if the
CPU usage step is 5%, the statistic 53% is rounded up to 55%, and the statistic 52% is rounded
down to 50%.
• The horizontal axis represents the time.
• Consecutive pound signs (#) indicate the CPU usage at a specific time. The value on the vertical
axis for the topmost pound sign at a specific time represents the CPU usage at that time.
