Metrics is data that is gathered from an agent. Typically, an agent is an application server, such as:

• a JBoss application server
• a Tomcat application server
• a WebSphere application server

For example, some possible metrics are:

• the agents memory usage
• the agents CPU utlization
• the agents garbage collection

Agents and the Enterprise Manager

On each server that contains agents, the /opt/wily/Introscope/core/config/IntroscopeAgent.profile file contains the configuration for all of the agents on the server. In the IntroscopeAgent.profile file, the hostname and port of the Enterprise Manager will be defined. The Enterprise Manager contains a central repository of the metrics from each agent.
