Monitoring Options Window of Performance Monitor
To start monitoring, select Enable for the Current Status option in
Monitoring Switch, and specify the Gathering Interval option to set the
interval for collecting information. Next, select or release the CUs to be
monitored in Monitoring Target area. You can specify target CUs either by
choosing PG numbers, LDKC numbers, CU numbers or the cells in the CU table.
For the details on how to select CUs, see Monitoring Options Window. After the
setting is completed, click Apply. Performance Monitor starts to obtain
statistics about the storage system and saves the statistics at the specified
interval.
If the number of CUs to be monitored is 64 or less, you can select a gathering
interval between 1 and 15 minutes. The gathering interval you selected here
determines the storing period of the statistics in short range, which is up to 15
days. For example, if you specify the gathering interval as 1 minute, the
statistics can be stored 1 day, and if you specify it as 15 minutes, the statistics
can be stored 15 days. If the number of the CUs to be monitored is 65 or more,
you can choose the gathering interval from among 5, 10 or 15 minutes. The
gathering interval you selected determines the storing period (between 8
hours and 1 day) of the statistics. In case of 510 CUs, for example, the
statistics can be stored for 8 hours if you specify the gathering interval to 5
minutes, and the statistics can be stored for 1 day if the interval is specified to
15 minutes.
