Use display flowengine-usage history to display the historical flow engine usage statistics.
The system regularly collects the 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,

rounded down to 50%.
