Event adapters acquire alarms from network devices, element managers, or other OSS systems, map the data into the VMware Smart Assurance format, and send it to a Topology Server that forwards it to the Analysis Server. Event adapters can acquire alarms in real time and/or periodically.

Event adapters can be implemented to support a variety of alarm sources including: flat file, XML, database, and API. Event adapters can support bulk loading, scoped loading, and events.
