Software monitoring with bounded overhead
In this paper, we introduce the new technique of HighConfidence Software Monitoring (HCSM), which allows one to perform software monitoring with bounded overhead and concomitantly achieve high confidence in the observed error rates. HCSM is formally grounded in the theory of supervisory control of finite-state automata: overhead is controlled, while maximizing confidence, by disabling interrupts generated by the events being monitored— and hence avoiding the overhead associated with processing these interrupts—for as short a time as possible under the constraint of a user-supplied target overhead Otarget. HCSM is a general technique for software monitoring in that HCSM-based instrumentation can be attached at any system interface or API. A generic controller implements the optimal control strategy described above. As a proof of concept, and as a practical framework for software monitoring, we have implemented HCSM-based monitoring for both bounds checking and memory leak detec...
