you want to generate or schedule a report.
If your favorite chart has more than 250 resources, HP XP P9000 Performance Advisor generates
a single report that will have the performance graphs for the 250 resources in the first chart followed
by the performance graphs for the remaining set of resources (beyond 250) in the subsequent
chart.
Can I generate reports for favorite charts created in previous versions of HP XP P9000 Performance
Advisor?
Yes. You can generate reports for favorite charts created in pre-4.6 version of HP XP P9000
Performance Advisor.
