Data Fundamentals

Systems Performance uses Performance Agents running on each monitored machine to collect data on a wide range of system and database resources, SAP resources, and SNMP‑based resources. There are two types of agents:

• Real-Time Performance Agent (prfAgent)
  This agent is responsible for the real‑time, transient collection of performance data, which it supplies to client applications such as Performance Scope.
• Historical Performance Agent (hpaAgent)
  This agent provides facilities for collecting, storing, and managing historical, time-banded data. Where necessary, it can act as a proxy to enable the monitoring of resources from SNMP-enabled hosts or devices that cannot support a Performance Agent directly, such as a network router.

For information on how to install and customize the Performance Agents, see the Inside the Performance Agent manual.
