HP XP P9000 Performance Advisor Software - Manual (Page 59)

Collecting performance data
After completing the configuration data collection for the XP and the P9000 disk arrays, schedule
the performance data collection for the associated components, which belong to the following
component types:
•
DKC
•
Ports
•
RAID Groups
•
Ext RAID Groups
•
THP pools
•
Snapshot pools
•
Cont. Access Journals
You can create two performance data collection schedules for an XP or a P9000 disk array, as it
enables you to frequently monitor the respective components. The components that are not selected
as part of the first schedule are automatically added to the second schedule. You can set different
collection frequencies to collect data for the DKC, ports, and the RAID groups. You can also enable
the schedules for automatic updates. The collection frequency set for a RAID group in a schedule
is applicable for any component of the continuous access journal, snapshot, ThP, and the external
RAID group types. It is applicable only if they are selected for performance data collection.
The following are important notes on the performance data collection:
•
The performance data collection does not start when the configuration data collection is in
progress. It starts automatically when the configuration data collection completes. If you set
the frequency of the configuration data collection schedule as one hour, then after every hour,
the performance data collection stops and restarts only when the configuration data collection
completes. On successful completion, the Event Log screen displays records for the generated
events. In case of performance data collection failure, the Event Log screen displays the failure
messages.
NOTE: If you plot performance graphs when the configuration data collection is in progress,
there are gaps in the data points. These gaps indicate that the performance data is not collected
during the configuration data collection time interval.
•
While creating a performance data collection schedule, you can select a command device
that is mapped through two different ports.
•
While creating performance data collection schedules, you cannot split the components
available in the respective component type lists into two schedules. For example, if you create
two performance data collection schedules, the components that you select from the DKC,
Port, and RG component type lists for the first schedule cannot be included in the second
schedule.
◦ If you create two performance data collection schedules in HP XP P9000 Performance
Advisor v5.5 and split the components, when you upgrade to HP XP P9000 Performance
Advisor v5.5.1 and modify a schedule, the following message is displayed when you
click Edit:
nl
This is a split schedule with the same component types added in
two schedules. HP recommends that you delete split schedules and
recreate schedules with the similar component types.

components that are split are removed, and the remaining components are saved in the
