HP StorageWorks P9000 Performance Advisor Software v5.3 User and Troubleshooting Guide (T1789-96322, August 2011)

In addition, the average usage summary for components is also derived from the set threshold duration
and verified against the threshold limits set for metrics in the particular category. Thereafter, the
statistics are displayed on the Dashboard screen.
IMPORTANT:
• The threshold duration is the period during which P9000 Performance Advisor monitors the point
in time and average usage of components, and determines the overall health of the XP or the
P9000 disk array.
• The average usage of components is monitored for those categories where threshold limits are
set for the corresponding metrics.
You can plot the usage graphs for components in the Chart Work Area and view the X busiest
components in the Component Information section of the Dashboard screen.
For more information on the sections in the Dashboard screen, see “Viewing dashboard” on page 128.
For more information on setting thresholds and specifying the X busiest components, see “Configuring
dashboard threshold settings” on page 122 and “Specifying the top 20 consumers” on page 125.
NOTE:
ACP and DKA, CHIP and CHA are terms that are used synonymously across the P9000 Performance
Advisor screens and in this user guide.
High-level steps for configuring threshold limits and viewing dashboard
The following are the high-level sequence of steps to configure the threshold settings and view the
overall usage summary of the XP and the P9000 disk arrays. The links at the end of each step direct
you to additional information related to that task:
1. On the Threshold Settings screen, enter the threshold limits and select the threshold duration for
the XP and the P9000 disk arrays. Specify the maximum and the least X busiest components you
want to view for a port, RAID group, or an MP blade (applicable only for the P9000 disk arrays).
For more information on specifying threshold limits and component settings, see “Configuring
dashboard threshold settings” on page 122 and “Specifying the top 20 consumers” on page 125.
