1: Monitor level
Parameters
task task-id: Displays the history statistics of the CPU usage of the specified task, where task-id
represents the task number. If the task-id argument is not provided, the system displays the history
statistics of the CPU usage of the entire system (the CPU usage of the entire system is the sum of
CPU usages of all tasks).
slot slot-number: Displays the history statistics of the CPU usage of the specified member device.
slot-number specifies the member ID of a device. You can use the display irf command to view the
member IDs of devices in a stack system. If the slot-number argument is not provided, the system
displays the history statistics of the CPU usage of the master.
cpu cpu-number: Displays the history statistics of the CPU usage of the specified CPU. If the
cpu-number argument is not provided, the system displays the history statistics of the CPU usage of
the main CPU.
Description
Use the display cpu-usage history command to display the history statistics of the CPU usage in a
chart.
If no argument is provided, the system displays the CPU usage of the master.
The system takes statistics of the CPU usage at an interval and saves the statistical results in the
history record area. You can use the display cpu-usage history command to display the CPU usage
statistics records during the last 60 minutes. The statistical results are displayed through geographical
coordinates. In the output information:
Latitude indicates the CPU usage, which is displayed based on the step. For example, if the step
of the CPU usage is 5%, then the actual statistics value 53% is displayed as 55%, and actual
statistics value 52% is displayed as 50%.
Longitude indicates the time.
Consecutive pond marks (#) indicate the CPU usage at a certain moment. The value of the
latitude corresponding to the # mark on the top of a moment is the CPU usage at this moment.
Examples
# Display the CPU usage statistics of the whole system.
