Monitoring is an important run time correctness checking mechanism. This paper introduces the notions of
monitorability
and
strong monitorability
for partially observable stochastic systems, and gives necessary and sufficient conditions characterizing them. It also presents important decidability and complexity results for checking these properties for finite state systems. Furthermore, it presents general monitoring techniques for the case when systems are modeled as quantized probabilistic hybrid automata, and the properties are specified as safety or liveness automata. Experimental results showing the effectiveness of the methods are given.
