Website Reliability Evaluation Based on Server Logs


An approach of determining website reliability is evaluated in this paper. This technique extracts the workload measures and various error codes from the server logs' data. This information is then used to calculate the reliability for the particular website. This study follows on forfrom another study, and hence, can be regarded as a partial replication of the original study. Although the method proposed by the original study is feasible, the effectiveness of just using a specific error type and a specific workload to estimate the reliability of websites is questionable. In this study, different error types and their usefulness for reliability analysis are examined and discussed. Potential issues with the workloads defined in the original study are also investigated and discussed. After a thorough investigation, we believe that reliability analysis for websites can and should be extended to include other error codes and workloads as they can provide a much better reliability estimate of today's highly dynamic websites.
