What is the main responsibility of the Overflow Filter in the Event Collector?

The Overflow Filter in the Event Collector is primarily responsible for enforcing the EPS (Events Per Second) license limit. This function is crucial because it helps maintain system performance and ensures compliance with licensing agreements. When the number of incoming events exceeds the specified EPS limit, the Overflow Filter will drop excess events to prevent overload on the system. This is important for maximizing efficiency and preventing data loss, while also adhering to the constraints set by the licensing model.

In contrast, other functions such as auto discovery of log sources, parsing of incoming events, and correlation of incoming events are handled by different components and processes within QRadar. Auto discovery involves identifying and configuring data sources, parsing is about interpreting the data format, and correlation deals with analyzing events for patterns or anomalies. Each of these functions serves a different purpose, which highlights why enforcement of the EPS limit is distinct and critical as a responsibility of the Overflow Filter.
