Use display cpu-usage history to display the historical CPU usage statistics in charts.
Syntax
display cpu-usage history [ job job-id ] [ slot slot-number [ cpu cpu-number ] ]
Views

Parameters
job job-id: Specifies a process by its ID. Without this option, the 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 an IRF member device by its member ID. Without this option, the command
displays the historical CPU usage statistics for the master device in the IRF fabric.
cpu cpu-number: Displays the historical CPU usage statistics for the specified CPU. The cpu-number
argument can only be 0.
Usage guidelines
After CPU usage monitoring is enabled, the system regularly samples CPU usage and saves the samples
to the history record buffer. This command displays the most recent 60 samples in a coordinate system
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.
