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.
