Comparison of techniques for diagnosing performance problems in information systems

Diagnosing performance problems is typically done using a structured (although heuristic) approach that exploits known relationships between measurement variables, represented by a measurement navigation graph (MNG). Since the results of a diagnosis depend critically on the arc weights, the focus of this work is on the evaluation of techniques that compute are weights. Detailed explanation on the different techniques used for diagnosing performance problems in computer systems is included in this paper.
