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
This storing period is the range of display in the Auto LUN windows. When you specify one minute for the
gathering interval like the example above, Performance Monitor can display the statistics for one day (that
is, 24 hours) in the list and graph at the maximum. Also, when you specify 15 minutes for the gathering
interval, Performance Monitor can display the statistics for 15 days in the list and graph at the maximum.
However, the value of the Gathering Interval option has nothing to do with the storing period of statistics
in long range monitoring. The gathering interval in long range is fixed to 15 minutes. Therefore, when
you select the longrange storing period in the Physical tab of Performance Monitor, the display range in
the window is always three months (that is, 93 days).
Note: The monitoring switch settings in the Monitoring Options window work in conjunction with the
monitoring switch settings in the Usage Monitor windows of Continuous Access, TrueCopy for Mainframe,
Continuous Access Journal, and Universal Replicator for Mainframe. Therefore, if you use the Monitoring
Options window to start or stop monitoring, or to change the gathering interval, the monitoring settings
of these remote copy functions will also change. Conversely, if the settings in each Usage Monitor
window are changed, the settings in the Monitoring Options window of Performance Monitor also
change automatically.
