Introduction
Reports provide history of performance data collected for a specified XP or a P9000 disk array,
where a visual representation of the performance trend of components is shown for a duration that
you specify. The performance data points are plotted for different metrics that help analyze the
performance of an XP or a P9000 disk array.
Reports can be a one-time activity, where you either generate and view a report, or save a copy
of the report for later reference.
•
If you generate a report, you can only view a temporary copy of the report. You cannot retrieve
the report once it is closed. For more information, see
“Generating, saving, or scheduling
reports” (page 300) .
•
If you save a report, it is available in the following location: Local_drive:\HPSS\pa\
tomcat\webapps\pa\export
. By default, the Local_drive on the management station
refers to the C drive, where the Windows operating system is installed and the HPSS folder
is also copied to the C drive. For more information, see
“Viewing a report” (page 308) .
Reports can also be a scheduled activity, where data is collected periodically on a daily, weekly,
or monthly basis. For more information, see
“Generating, saving, or scheduling reports” (page 300) .
Types of reports
Reports in HP XP P9000 Performance Advisor provide a high level performance view of the XP
and P9000 disk arrays, and the utilization of individual components in these disk arrays. Each
report includes the 50th, 90th, and 95th percentile values as legends in the charts. Following are
the different reports that you can view in HP XP P9000 Performance Advisor. The Yes and No
given under For XP disk arrays and For P9000 disk arrays columns indicate whether that particular
report is displayed for the XP or the P9000 disk array:
