Default Level
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).
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 whole system.
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 in 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.
