SCAPE

I was involved in this project as a research assistant at the University of Stuttgart with two friends of mine. Together, we programmed the framework and conducted the experiments which are reported in a paper published in the ValueTools 2014 conference.

Used technologies include: Java, Weka machine learning library, the Kieker framework, and the R language for the evaluation/plotting of the experimental results.

Paper Abstract

During operation, software systems produce large amounts of log events, comprising notifications of different severity from various hardware and software components. These data include important information that helps to diagnose problems in the system, e.g., post-mortem root cause analysis. Manual processing of system logs after a problem occurred is a common practice. However, it is time-consuming and error-prone. Moreover, this way, problems are diagnosed after they occurred|even though the data may already include symptoms of upcoming problems.

To address these challenges, we developed the SCAPE approach for automatic system event classification and prediction, employing machine learning techniques. This paper introduces SCAPE, including a brief description of the proof-of-concept implementation. SCAPE is part of our Hora framework for online failure prediction in component-based software systems. The experimental evaluation, using a publicly available supercomputer event log, demonstrates SCAPE's high classification accuracy and first results on applying the prediction to a real-world data set.
