Abstract

Failure phenomena of web server systems are considered to depend on their workload characteristics. In this paper we focus on the Apache server system and analyse the real access/error logs. Based on parametric and non-parametric statistics, we characterise the web server failure from both theoretical and empirical points of view. As the result, it can be shown that the number of sessions strongly affects to the failure rate property of the Apache server.
