Introduction
XP Performance Advisor does real-time monitoring of XP arrays, where performance data is collected
for intervals as low as few seconds (approximately, 5 seconds per resource). Real-time data is collected
through the following XP Performance Advisor host agents that support real-time performance data
collection:
• Windows hosts
• Linux hosts
• Solaris hosts
• HP-UX hosts
When you perform host agent installation, real-time server is also automatically installed on the host
agent. For more information on host agent installation, refer to the HP StorageWorks XP Performance
Advisor Software Installation Guide. You can collect the real-time performance data for a set of 5
LDEVs or RAID groups belonging to an XP array. This data is collected for a set of real-time metrics
that XP Performance Advisor supports. When you start a real-time performance data collection for an
XP array, the following sequence of steps follows:
1. The associated host agent collects real-time performance data from the XP array and sends it to
XP Performance Advisor.
2. XP Performance Advisor plots a graph of the real-time performance data points. This process
continues till you stop the real-time data collection.
