Abstract:This paper develops and validates a methodology to detect small, incipient faults in software systems. Incipient faults such as memory leaks slowly deteriorate the software's performance over time and if left undetected, the end result is usually a complete system failure. The proposed method combines tools from information theory and statistics: entropy and principal component analysis (PCA). The entropy calculation summarizes the information content associated with the collected low-level metrics and reduces… Show more
