Beacons are specific modules that reside within an Oracle Management Agent and are capable of different service tests at periodic intervals. Beacons collect and upload the availability and performance metrics for various service tests through the agent transport mechanism. As discussed before, the same beacon can execute different service tests of different service targets. For monitoring and modeling purposes, the beacons themselves are modeled as targets in OEM Grid Control.
Just like any other target, the beacon targets also have a home page displaying consolidated monitoring information in the context of the specific beacon.
