Analysis of service diagnosis improvement through increased monitoring granularity

Due to their loosely coupled and highly dynamic nature, service-oriented systems offer many benefits for realizing fault tolerance and supporting trustworthy computing. They enable automatic system reconfiguration when a faulty service is detected. Spectrum-based fault localization (SFL) is a statistics-based diagnosis technique that can be...

Revisiting the Practical Use of Automated Software Fault Localization Techniques

In the last two decades, a great amount of effort has been put in researching automated debugging techniques to support developers in the debugging process. However, in a widely cited user study published in 2011, Parnin and Orso found that research in automated debugging techniques made assumptions that do not hold in practice, and suggested...

Automated Fault Localization for Service-Oriented Software Systems

In this thesis, we have focused on applying Spectrum-based Fault Localization (SFL) to diagnose Service-Oriented Systems at runtime. We reused a framework-based online monitoring technique to obtain the service transaction information. We devised a three-phased oracle and combined this with monitoring to detect system failures at runtime. Both...

Spectrum-based Fault Diagnosis for Service-Oriented Software Systems

Preprint of paper published in: 5th IEEE International Conference on Service-Oriented Computing and Applications (SOCA), 17-19 December 2012; doi:10.1109/SOCA.2012.6449440 Due to the loosely coupled and highly dynamic nature of service-oriented systems, the actual configuration of such system only fully materializes at runtime, rendering many of...

Spectrum-based Fault Localization in Embedded Software

Locating software components that are responsible for observed failures is a time-intensive and expensive phase in the software development cycle. Automatic fault localization techniques aid developers/testers in pinpointing the root cause of software failures, as such reducing the debugging effort. Automatic fault localization has been an...

On the Performance of Fault Screeners in Software Development and Deployment

Preprint of paper published in: ENASE 2008 - Proceedings of the 3rd International Conference on Evaluation of Novel Approaches to Software Engineering, 4-7 May 2008 Fault screeners are simple software (or hardware) constructs that detect variable value errors based on unary invariant checking. In this paper we evaluate and compare the...
