Abstract: To extract useful performance indicators from business process, this paper develops a new approach to monitor business process using Web Service Proxy(WS-Proxy). WS-Proxy provides a single point of service access with service mapping, message dispatching and data extracting functions. It utilizes a DFA-based algorithm developed based on YFilter for monitoring Web service messages and extracting XML elements. Experimental results show WS-Proxy achieves better performance than YFilter in processing SOAP messages.

摘要： 为了能高效地从业务流程中抽取出所需的绩效指标，提出利用Web service代理(WS-Proxy)对基于Web service的业务流程进行监控。WS-Proxy提供单一的服务访问点，实现服务映射、消息转发和数据抽取。在YFilter的基础上开发基于DFA的抽取算法，WS-Proxy可以利用该算法高效地对Web service消息进行检查，对消息中的XML元素内容进行抽取。实验证明，WS-Proxy在处理SOAP消息时比YFilter具有更高的效率。
