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”onpage42.

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.
