Description
Use the display cpu-usage history command to display the history statistics of the CPU usage in a
chart. If no argument is specified, the CPU usage of the active main board is displayed.
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 last 60 CPU
usage statistics records. 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.
