Using the Performance Manager GUI 4-29
Hitachi Universal Storage Platform V/VM Hitachi Performance Manager User’s Guide
This storing period is the range of display in the Performance Management
windows. When you specify one minute for the gathering interval like the
example above, Performance Monitor can display the statistics for one day (i.e.
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 (i.e., 93 days).
The monitoring switch settings in the Monitoring Options window work in
conjunction with the monitoring switch settings in the Usage Monitor
windows of TrueCopy, TrueCopy for IBM z/OS, Universal Replicator, and
Universal Replicator for IBM z/OS. 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.
