DRiVeR: Diagnosing Runtime Property Violations Based on Dependency Rules

To ensure the reliability of complex software systems, runtime software monitoring is widely accepted to monitor and check system execution against formal properties specification at runtime. Runtime software monitoring can detect property violations, however it can not explain why a violation has occurred. Diagnosing runtime property violations is still a challenge issue. In this paper, a novel diagnosis method based on dependency rules is constructed to diagnose runtime property violations in complex software systems. A set of rules is formally defined to isolate software fault from hardware fault, then software faults is localized by combining trace slicing and dicing. The method is implemented in the runtime software monitoring system SRMS, and experimental results demonstrate that the method can effectively isolate and locate the related faults with property violations.
