Moreover, the resource usage in the storage system can also be stored in a long range up to 3 months.
In this case, however, the gathering interval is fixed to 15 minutes regardless of the value set for the
Gathering Interval option. For details on the relationship of collection interval and storing period of the
statistics, see “ Monitoring Options Window ” on page 42.
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 will also
change automatically.
