Introduction
XP Performance Advisor interacts with XP arrays through hosts that have operating system specific XP
Performance Advisor host agents installed. These hosts form the channel of communication between
XP Performance Advisor and XP arrays. Once the host agents are installed, the corresponding records
automatically appear under the Host Information tab on the Array View screen. The associated XP
array configuration summary details are also displayed on the relevant XP Performance Advisor
screens. If command devices are configured on XP arrays, the corresponding command device details
are displayed for each XP 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 configuration changes to the host
agent or their associated XP arrays. You can remove records for host agents that are no longer
connected to the management station.
After the host agents are discovered, you can start configuration data collection and performance
data collection for an XP array using its corresponding command device. Configuration data collection
can be a one-time activity or scheduled periodically on a daily, weekly, or monthly basis. It can be
collected using the Inband or OutBand mode of data collection. During scheduled configuration data
collection for an XP array, data pertaining to the new resources in an XP array are automatically
included in the latest configuration data. During one-time configuration data collection, data on new
resources 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, you can start performance data collection for an
XP array by creating a schedule and including resources that need to be monitored. You can collect
performance data for RAID groups, disk controller units (DKC), ports, XP Continuous Access Journal,
ThP, and External RAID groups. In addition, you can also specify the frequency of collection for each
of the selected resources. Further, you can enable a performance data collection schedule to
automatically monitor and collect performance of new resources (RAID groups and ports). Resources
discovered during the scheduled configuration data collection are automatically added to the
performance data collection schedules that are enabled to automatically monitor new resources. For
more information, see “Enabling performance collection schedules for automatic updates” on page 56.
Confirmatory records on all events generated for host updates, configuration, and 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 144.
