The CoCoME case study comprises an architectural model defined with the Palladio Component Model (PCM), augmented with a behavior language (BL) and a data type language (DTL). As CoCoME is based on an enterprise application scenario, we want to monitor its usage and behavior. Therefore, we utilize the monitoring framework Kieker and the adjunct DSLs for record specification (IRL) and the specification of advises and sensor placement (IAL).
