HP StorageWorks XP Performance Advisor Software v4.6 User and Troubleshooting Guide (T1789-96094, June 2010)

IMPORTANT:
• The link to the Threshold Settings screen is available on the Dashboard screen, only if you have
logged in as the default Administrator or as a user who is granted administrative privileges.
• XP Performance Advisor retrieves usage data for resources belonging to those categories for which
the threshold limits are specified. It is mandatory that the threshold limit be specified for at least
one metric in a category of your choice.
• By default, XP Performance Advisor retrieves data for the past six hours from the time you saved
the threshold settings. It considers the management station time to calculate the threshold duration.

“Setting performance threshold limits” on page 102.
