Runtime monitoring is a fundamental technique used throughout the lifecycle of a system for many purposes, such as debugging, testing, or live analytics. While runtime monitoring for general purpose programming languages has seen a great amount of research, developing such complex facilities for any executable Domain Specific Language (DSL) remains a challenging, reoccurring and error prone task. A generic solution must both support a wide range of executable DSLs and induce as little execution time overhead as possible. Our contribution is a fully generic approach based on a temporal property language with a semantics tailored for runtime verification. Properties can be compiled to efficient runtime monitors that can be attached to any kind of executable discrete event model. Efficiency is bolstered using a novel combination of structural model queries and complex event processing. Our evaluation on 3 executable DSLs shows that the approach is applicable with an execution time overhead of 121% (on executions shorter than 1s), to 56% (on executions shorter than 20s) making it suitable for model testing and debugging.

As explained in the paper, we implemented our approach as a tool provided inside the GEMOC Studio, an Eclipse-based language and modeling workbench to design executable DSLs and execute conforming models. Here is a screenshot of the GEMOC Studio when debugging and monitoring properties on an Activity Diagram model taken from the evaluation materials:
