SOA has been widely used nowadays in a variety of e-business applications which interoperability crosses systems andrnorganisations. The demand of tracking and monitoring the business data involved in multi-party collaboration is growing up. The main difficulties of business activity monitoring are how to acquire the data from business applications and to define the target tracking. In this article we propose a novel method that defines the target monitoring object based on WS-CDL model, and obtains the run-time data by intercepting network data packet. It gets rid of the repeated development of different monitoring adapters for different business processes. The architecture of the monitoring system, the rules of defining monitoring objects and the algorithm of interaction messages capture are all described in this article.%当前SOA架构已经广泛地应用于各种跨系统、跨组织的电子商务.对多方协同中所涉及到的业务数据进行跟踪与监控的需求日益增长.业务活动监控的主要难点是如何从商业应用中获取数据以及定义跟踪目标.提出基于WS-CDL模型对监控目标进行定义,截取网络包数据获得运行时数据的新方法.该方法避免为不同的业务流程重复性的开发不同监控适配器.对监控系统的架构、监控目标定义规则以及交互消息捕获算法进行阐述.
