Parameters
task task-id: Displays the historical CPU usage statistics for the specified task. The task-id argument
represents the task number. If no task is specified, the command displays the historical CPU usage
statistics for the entire system. The CPU usage of the entire system is the sum of CPU usages of all tasks.
slot slot-number: Displays the historical CPU usage statistics for the specified card. The slot-number
argument represents the IRF member ID of the switch. If no member switch is specified, the command
displays the historical CPU usage statistics for the active MPU. (In standalone mode)
chassis chassis-number slot slot-number: Displays the historical CPU usage statistics for the specified card
on an IRF member switch. The chassis-number argument represents the IRF member ID of the switch, and
the slot-number argument represents the number of the slot that holds the card. If no card is specified, the
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 no CPU is specified,
the command displays the historical CPU usage statistics for the main CPU.
|: Filters command output by specifying a regular expression. For more information about regular
expressions, see Fundamentals Configuration Guide.
begin: Displays the first line that matches the specified regular expression and all lines that follow.
exclude: Displays all lines that do not match the specified regular expression.
include: Displays all lines that match the specified regular expression.
regular-expression: Specifies a regular expression, a case-sensitive string of 1 to 256 characters.
Description
Use the display cpu-usage history command to display historical CPU usage statistics in charts.
The system regularly collects CPU usage statistics and saves the statistics in the history record area. The
display cpu-usage history command displays the CPU usage statistics for the last 60 minutes in axes,
where:
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 # sign at a specific time represents the CPU usage at that time.
