Runtime monitoring and dynamic performance attributes data acquisition of Web services

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.
