System Call Logs with Natural Random Faults: Experimental Design and Application

In this paper we present a large dataset for use in embedded systems research which has been gathered from a realistic development environment operating in the path of an accelerated neutron beam. The dataset contains traces with events from a real-time operating system as well as user events from a safety critical application. All data is carefully timestamped and in human understandable form. We present two use cases for this dataset: mining timed regular expressions to extract system specifications from clean and possibly anomalous data generated during the operation of the neutron beam, and runtime monitoring to extract information from traces with incomplete information.
