摘要
为保证Web服务业务流程及时、准确地获得所调用服务的性能状况,提出了一种轻量级的Web服务运行时的监控和性能数据动态采集框架。该框架采用面向方面的编程,将方面代码植入业务流程执行语言的Web服务消息调用处,以收集服务实例执行状态、时间、事件信息,据此进一步计算出服务性能指标。监控独立于流程本身的运行,实现了服务调用逻辑与监控逻辑的分离。通过实验验证了该方法的可行性,表明监控代价是可以接受的。
To guarantee Web services process obtaining performance status of called service timely and accurately,a lightweight Web services runtime monitoring and dynamic performance attributes data acquisition framework in Business Process Execution Language（BPEL） was presented.This framework adopted an aspect-oriented programming,and aspect-oriented code was implanted in BPFL Web Service message.Execution status,time,event information were collected,then service performance was calculated.Monitoring was operated independently from process,so that service call logic and monitoring logic was separated.Examples were used to suggest that this approach was feasible,and the monitoring cost was affordable.
