Usage guidelines

The system regularly collects flow engine usage statistics and saves the statistics in the history record area.

The display flowengine-usage history command displays the flow engine usage statistics for the last 60

minutes in axes, where.

• The vertical axis represents the flow engine 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 flow engine usage at a specific time. The value on the

vertical axis for the topmost # sign at a specific time represents the flow engine usage at that time.
