5 Collecting real-time performance data
from XP and P9000 disk arrays
This chapter discusses the following topics:
• “Introduction” on page 83
• “Starting real-time performance data collection” on page 85
• “Stopping real-time performance data collection” on page 89
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
When you perform the host agent installation, the real-time server is also automatically installed on
the host agent. For more information on the host agent installation, refer to the HP StorageWorks
P9000 Performance Advisor Software Installation Guide. You can collect the real-time performance
data for a set of five LDEVs or RAID groups in an XP or a P9000 disk array. This data is collected for
a set of real-time metrics that P9000 Performance Advisor supports. When you start a real-time
performance data collection for an XP or a P9000 disk array, the following sequence of steps follows:
1. The associated host agent collects real-time performance data from the XP or the P9000 disk array
and sends the data to P9000 Performance Advisor.
2. P9000 Performance Advisor plots a graph of the real-time performance data points. This process
continues till you stop the real-time data collection.
