A runtime software monitoring cost analysis method

Pointing to the problem of extra monitoring cost of injected runtime software monitoring technologies, this paper proposes a method MCAM, which is used to analyze the extra software monitoring cost. Analyzing and disposing obtained monitoring information, reducing to inject the unnecessary monitoring probes; we propose an optimization analysis method OCAM, which can reduce the software monitoring cost at a certain extent. MCAM and OCAM are mainly based on three factors, software complexity, user monitoring requirement, and execution traces. Based on these factors, this paper gives out the formal definitions and analysis processes of the two methods. Experiment result shows that software monitoring cost computed by OCAM is smaller than computed by MCAM.
