show historical_utilization
Description
This command is used to display the historical utilization of CPU and memory. There are two kinds
of statistics offered, 15-minute based and 1-day based. For statistics based on 15 minutes, there
are 96 counting slots for the historical statistic count. Suppose that the system has been up for
more than 75 mins, then slot 1 refers to the time since 15 minutes ago until now, and slot 2 refers
to the time since 30 minutes ago until 15 minutes ago. For statistics based on a day, there are two
counting slots for the historical statistic count. The statistics for the utilization count the average of
CPU utilization and average of memory usage rate in that time slot.
