3.1.1. Components Entities

An Entity is a module that performs data collection on one particular item, such as CPU usage, memory, or Web site reachability. When the Agent picks up its configuration from the Server, it looks to see which Entities have been configured, then runs them in turn to collect information. Once all the Entities have run, it contacts the Server and uploads the information. This information packet is known as a 'report'. If the Agent does not send in reports after a set period (default is approximately 10 minutes), the Server sends a notification that the agent is "not reporting in."
