Event Driven Monitoring for Service Composition Infrastructures

We present an event-based monitoring approach for service composition infrastructures. While existing approaches mostly monitor these infrastructures in isolation, we provide a holistic monitoring approach by leveraging Complex Event Processing (CEP) techniques. The goal is to avoid fragmentation of monitoring data across different subsystems in large enterprise environments by connecting various event producers. They provide monitoring data that might be relevant for composite service monitoring. Event queries over monitoring data allow to correlate different monitoring data to achieve more expressiveness. The proposed system has been implemented for a WS-BPEL composition infrastructure and the evaluation demonstrates the low overhead and feasibility of the system.
