Abstract

Quality of service (QoS) is adopted widely in Web services research and practice for various purposes such as for metadata publishing and operational management of Web services. Nonetheless, current tools for monitoring and gathering QoS information support only a limited number of QoS attributes (e.g. response time, successful execution rate, availability) and therefore can neither well keep up to the QoS models proposed in several researches nor to the requirements in practical use. This paper reviews a QoS model which covers various dimensions of service quality (i.e. availability, accessibility, performance, reliability, security, and regulatory) and proposes metrics to enhance QoS measurement on the service side. A monitoring tool is designed and developed as an extension to Web services monitoring feature of Java System Application Server under Sun’s GlassFish project.
