QoS collection for web services based on WS-monitor model

Abstract

QoS information is often used as the basic evidence for Web services optimization. In order to collect QoS information of Web services, we propose a lightweight Server-Monitor framework. This proposal contains a WS-Monitor Model related to metamodel of QoS index information and an extending WSDL algorithm that adds QoS collect strategy into WSDL. Experimental results show that Server-Monitor obtains QoS information effectively and causes tiny negative effect on Web service.
