1. Collecting information about the XP disk arrays you will be monitoring on page 20
2. Determining the management station and host requirements on page 20
3. Preparing your XP disk arrays and determining their data collection schedules on page 22
Collecting information about the XP disk arrays you will be monitoring
1. Determine the number of logical devices (LDEVs) for each of the XP disk arrays.
2. Determine how frequently you want to access data from the XP disk arrays.
IMPORTANT:
The rate of data collection can affect the loads seen by the management station and the XP
disk arrays.
XP Performance Advisor provides the following types of data collection:
• Configuration data collection:
The frequency of configuration data collection depends on how often you change the configuration
of an XP Disk Array. For example, if you add a LUN to an XP Disk Array every week, you may
collect configuration data at least once a week to see the changes reflected in your XP Performance
Advisor database.
• Performance data collection:
• For troubleshooting XP Disk Array performance issues, HP recommends a collection frequency
of 1 to 3 minutes.
IMPORTANT:
Frequent collection increases the load on your management station and the XP disk arrays.
For real-time troubleshooting, HP recommends using XPWatch, which is one of the utilities
included in XP Performance Advisor to collect real-time performance data for troubleshooting
purpose.
• For general monitoring and forecasting resource utilization, HP recommends a collection fre-
quency of 5 - 30 minutes.
Determining the management station and host requirements
Follow these steps to determine your management station and host setup requirements:
1. Check the supported configuration for management station and host agent. For more information,
see “Verifying the supported configurations for XP Performance Advisor” on page 23 and
“Verifying the supported configurations for XP Performance Advisor host agents” on page 33.
