Multidimensional Log Analysis

Abstract

Various event and performance logs are available in computer systems. They are considered as useful data source characterizing system operational profiles and possible anomalies. In the literature different classes of logs are usually analyzed separately and targeted at some specific problems. We have developed analysis schemes and tools which facilitate studying these logs in a holistic way taking into account various observation perspectives and cross relations as well as different analysis goals. This approach has been verified for some computer systems of the University and industry.
