为了提供对基于web service业务流程的有效监控,开发了web service代理(WS-proxy)用于监控服务的交互进而监控业务活动的绩效.WS-proxy以中间结点的形式部署在内部的业务流程和外部的服务提供者之间,同时它提供了消息路由和消息内容检查功能.通过利用一个XPath引擎(WS-filter),它可以将绩效指标数据从服务消息中抽取出来进而评估业务绩效.在实验中,WS-proxy的可用性和监控效率得到了验证.WS-proxy带来的延迟大约只占到整体延迟的15%,并且抽取绩效指标数据仅消耗了不到1/3的处理时间.
In order to provide effective monitoring of business processes based on web services, a web service proxy (WS-proxy) was developed to monitor service interactions and monitor the performance of business activities.WS-proxy is deployed as an intermediate node in internal business processes And external service providers, and it provides message routing and message content checking capabilities, which take advantage of an XPath engine (WS-filter) that pulls performance metric data out of service messages to assess business performance. In the experiment, the availability and monitoring efficiency of WS-proxy were verified, and the delay caused by WS-proxy accounted for only about 15% of the overall delay and the performance indicator data was extracted using less than 1/3 of the processing time.
