Performance Monitor has two kinds of periods (ranges) for collecting and
storing statistics: short range and long range.
The storing period of statistics in short range is determined by the settings of
Gathering Interval option. Performance Monitor saves the statistics obtained
up to 1440 times in SVP. Therefore, you can estimate the storing period of
statistics with "gathering interval multiplied by 1440". For example, if you
specify one minute for the gathering interval, the statistics for one day can be
stored at the maximum from the following formula:
1 minute x 1440 = 1440 minutes = 24 hours = 1 day
