task number. If the task-id argument is not provided, this command displays the historical CPU usage

statistics for the entire system (the CPU usages of the entire system is the sum of CPU usages of all tasks).

expressions, see Getting Started Guide.

Description

Use display cpu-usage history to display historical CPU usage statistics in a chart. If no argument is

provided, the system displays the historical CPU usage statistics of the whole system.

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.
