Abstract :
In this article we describe the event streaming functionality as implemented in the ATLAS online system. Event streaming allows real-time classification and distribution of raw events into different subsets based on the decisions taken by the trigger system. Use cases, requirements and implementation of the main features are discussed. Furthermore, we present the ATLAS commissioning and monitoring activities related to event streaming.
