A Monitoring Tool for a Branching-Time Logic
We present the implementation of an experimental tool that automatically synthesises monitors from specifications written in mHML, a monitorable subset of the branching-time logic \(\mu \)HML. The synthesis algorithm is compositional wrt the structure of the formula and follows closely a synthesis procedure that has been shown to be correct. We discuss how this compositionality facilitates a translation into concurrent Erlang monitors, where each individual (sub)monitor is an actor that autonomously analyses individual parts of the source specification formula while still guaranteeing the correctness of the overall monitoring process.
