Executive Summary

Runtime verification as a field faces several challenges. One key challenge is how to keep the overheads associated with its application low. This is especially important in real-time critical embedded applications, where memory and CPU resources are limited. Another challenge is that of devising expressive and yet user-friendly specification languages that can attract software engineers. In this paper, it is shown that for many systems, in-place logging provides a satisfactory basis for postmortem "Run-time" verification of logs, where the overhead is already included in system design.
