A Case Study on Optimizing Web Service Monitoring Configurations

Abstract

Whilst monitoring web services provides benefits in terms of demonstrating that Service Level Agreements (SLAs) have been met, monitoring comes with a cost on the QoS of delivered services. We present the application of our method for optimizing the configuration of a suite of web service monitors in order to minimise the QoS impacts of monitoring on a web service provider. We discuss the actions required for optimization, and benefits that were achieved. Through this case study, we highlight the possible benefits of optimization to a web service provider, and give details on how we achieve optimization.
