In addition, you can also view the All report that provides the above mentioned report types (except
for the LDEV Activity report) in a single report document.
Reports can be a one-time activity, where you generate and view a report or save and view a report.
• If you generate a report, you can only view a temporary copy of the report. You cannot retrieve
the report once you close the report. For more information, see “Generating, saving, or scheduling
reports” on page 260.
• If you save a report, XP Performance Advisor retains a copy of the report in the following location:
Local_drive:\HPSS\Tomcat\Webapps\PA\Reports, and provides the report whenever
you want to view the report. Here, Local_drive on the management station refers to the C drive,
where Windows operating system is installed, and the HPSS folder is also copied to the C drive.
For more information, see “Viewing a report” on page 268.
Reports can also be a scheduled activity, where data is collected periodically for the duration that
you specify (on a daily, weekly, or monthly basis) and automatically provided in reports. For more
information, see “Generating, saving, or scheduling reports” on page 260.
