Troubleshooting using real-time performance data from XP and
P9000 disk arrays
This chapter discusses troubleshooting issues for disk array components using the real-time charting
feature in P9000 Performance Advisor.
Introduction
P9000 Performance Advisor does real-time monitoring of the XP or the P9000 disk arrays, where
performance data is collected for intervals as low as few seconds (approximately, five seconds per
component). The real-time data is collected through the following P9000 Performance Advisor host
agents that support the real-time performance data collection:
• Windows hosts
• Linux hosts
• Solaris hosts
• HP-UX hosts
• AIX hosts
• OpenVMS Integrity (IA-64) hosts
