7. Set the frequency in minutes for the DKC, RAID groups, and the port performance data collection
by selecting the frequency from the respective Frequency list.
8. Select the check box for Stagger Schedule if you want to stagger the data collection time at
different intervals.
For example, Stagger Schedule check box is not selected, and Frequency is set to 15 minutes,
performance data collection occurs at every quarter, irrespective of when the schedule is created.
Example, if the schedule is created at 10.12 a.m., the first collection occurs immediately and the
next collection occurs at the quarter of the hour, which is 10.15 a.m. The subsequent collection
occur at 10.30 a.m., 10.45 a.m., and so on. If you check Stagger Schedule, performance data
collection occurs every 15 minutes from the time the schedule is created. For example, if the
schedule is created at 10.12 a.m., the first collection occurs immediately, and the next collection
is 15 minutes later, at 10.27 a.m. The subsequent collection take place every 15 minutes after
that.
The Stagger Schedule ensures that the load on the management server is balanced, because the
data collection occurs for all the XP and the P9000 disk arrays at varied points of time in the
day and not every 15 minutes of the hour.
9. Select the Add new RAID Groups, Ports to this schedule check box, if you want the performance
data collection schedule to automatically collect the performance data for the new RAID groups
or the ports that are discovered during the scheduled configuration data collection. If the Add
new RAID Groups, Ports to this schedule check box is selected in the first schedule, it is
automatically disabled in the second schedule.
However, the new ThP, snapshot, continuous access journal volumes, and the external RAID
groups are automatically added to that performance data collection schedule, which is already
collecting data for other virtual volumes that belong to the same XP or P9000 disk array.
10. Click Save for the changes to take effect.
Click Cancel, if you do not want to configure a schedule for the current selection.
Click Refresh to view the updated list of performance data schedules.
