Abstract:
Logging is a common method to monitor the operation of a system and to identify failures of services and system components. When developing software for an embedded system there are stricter restrictions that result from the limited hardware resources. The performance of the hardware as well as the available memory is limited. Furthermore, embedded systems are often not accessible for a long period of time. This paper presents tools to improve existing logging methods without compromising existing development flows. Essentially, these tools on one hand transparently pre-process the source code in order to optimize logging instructions and add on the other hand a post-processing step when analyzing log-files. The presented tools were evaluated by integrating them to an industrial project where they show a significant improvement of the logging performance.
