HP XP P9000 Performance Advisor Software v6.0 User Guide

NOTE:
The THP Group(s), CA Journal Group(s), and the SNAP Group(s) component type lists are
displayed only if the corresponding components are configured on the selected XP or the
P9000 disk array. The External RG(s) component type list is displayed only if the external
volumes are attached to the selected XP or the P9000 disk array.
Selecting a ThP, snapshot, or a continuous access journal volume also provides the
respective volume pool information.
To select all components, select the check box next to the component type.
“Performance Data Collection” (page 62) shows scheduling performance data collection for

7. Set the frequency in minutes for the DKC, RAID groups, and the port performance data collection
by selecting the frequency in the respective Frequency list.
8. Select the Stagger Collection check box if you want to stagger the data collection time at
different intervals.
For example, if the Stagger Collection check box is not selected, and Frequency is set to 15
minutes, performance data collection occurs every fifteen minutes, irrespective of when 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 occurs at the quarter of the hour, which is 10.15
a.m. The subsequent collections occur at 10.30 a.m., 10.45 a.m., and so on. If you select
Stagger Collection, 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
collections take place every 15 minutes after that.
The Stagger Collection 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 for every 15 minutes in an hour.
9. Select the Add new RGs and Ports to the schedules that have RG and Port components enabled
check box if you want to update the new RAID groups or port components that are discovered
during the scheduled performance data collection to the appropriate schedule. The newly
