Efficient and safe operation of Intelligent Transportation Systems (ITS) has significant impact on the life of citizens and economies. A wide range of technologies, aka. Operational Technologies (OT) (e.g., sensors, actuators or network routers), are employed for monitoring and controlling the operation of ITS, being, due to the convergence with Information Technology (IT), more and more based on the Internet-of-Things (IoT) paradigm. Monitoring the service quality of OT, i.e., Operational Technology Monitoring (OTM), is a crucial prerequisite for ensuring efficient and safe operation. OTM from an industry perspective, however, faces some challenges, which are, despite their importance for ITS operators, not sufficiently addressed by now.
