Applying time series analysis to performance logs
Marcin Kubacki, Janusz S. Sosnowski · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2015
Contemporary computer systems provide mechanisms for monitoring various performance parameters (e.g. processor or memory usage, disc or network transfers), which are collected and stored in performance logs. An important issue is to derive characteristic features describing normal and abnormal behavior of the systems. For this purpose we use various schemes of analyzing time series. They have been adapted to the specificity of performance logs and verified using data collected from real systems. The presented approach is useful in evaluating system dependability.
