The Use of Event Logs for Software Reliability Analysis of Fielded
Systems
Philips Healthcare produces high-end X-ray systems that are
used to visualize arteries in the human body. Monitoring and constantly improving the
reliability of these systems is of great importance to Philips Healthcare. In modern systems,
the reliability is determined both by the hardware and software, and their complex interactions.
In the past, much focus has been given on quantifying and understanding the hardware reliability
of fielded systems, but not much was done to analyze the reliability of the software. However,
due to modern Internet technologies, event logs generated by the system’s software have become
more easily available and can be used for reliability analysis. This presentation focuses on
the use of event logs for software reliability analysis, the difficulties in doing so and
some first encouraging results.
