Collecting data without using an agent
Agentless data collection is currently available for systems that run supported versions of Microsoft
Windows and that are licensed for Capacity Advisor. These managed systems are automatically
configured for agentless data collection by the Insight managed system setup wizard. A service
— the HP Agentless Data Collector Service — makes the collected data available to the “HP
Capacity Advisor Data Collection Service” (page 39).
