Introduction
P9000 Performance Advisor interacts with the XP and the P9000 disk arrays through hosts that have
the operating system specific P9000 Performance Advisor host agents installed. These hosts form the
channel of communication between P9000 Performance Advisor and the XP and the P9000 disk
arrays. Once the host agents are installed, the corresponding records automatically appear under
the Host Information tab on the Array View screen. The configuration summary details of the associated
XP and the P9000 disk arrays are also displayed on the relevant P9000 Performance Advisor screens.
If command devices are configured on the XP and the P9000 disk arrays, the corresponding command
device details are displayed for each XP and P9000 disk array record under the Configuration Data
tab on the Array View screen. You can request an update from a host agent every time you make the
configuration changes to the host agent or their associated XP and the P9000 disk arrays. You can
remove records for the host agents that are no longer connected to the management station.
After the host agents are discovered, start the configuration data collection followed by the performance
data collection for an XP or a P9000 disk array using its corresponding command device. The
configuration data collection can be a one-time activity or scheduled periodically on a daily, weekly,
or a monthly basis. It can be collected using the inband or the outband mode of data collection.
During a scheduled configuration data collection, the data pertaining to the new components are
automatically included in the latest configuration data. During a one-time configuration data collection,
the data on new components cannot be collected after the configuration collection is complete. You
must perform another one-time configuration data collection to receive the updated configuration
data.
After the configuration data collection is complete, start the performance data collection by creating
schedules and including components that need to be monitored. You can collect performance data
for the RAID groups, DKCs, ports, continuous access journals, ThP, and the external RAID groups. In
addition, you can also specify the frequency of collection for each of the selected components. Further,
you can enable a performance data collection schedule to automatically monitor and collect the
performance of new components (RAID groups and ports). The components discovered during the
scheduled configuration data collection are automatically added to the performance data collection
schedules that are enabled to automatically monitor new components. For more information, see
“
Enabling performance collection schedules for automatic updates ” on page 78.
Confirmatory records on all the events generated for host updates, configuration, and the performance
data collection activities are displayed on the Event Log screen. To view the Event Log screen, click
Event Log in the left pane. For more information on managing events, see “
Viewing events ” on page 157.
