一种面向Web复合服务的运行时监控方法

随着计算机技术的发展,软件面临着日益严峻的可信性要求,运行时监控技术作为保证软件可信性的一个重要方法,已受到人们的普遍关注。分析总结传统软件运行时监控技术的基本问题和方法,给出运行时监控的基本视图。针对Web复合服务面临的特殊运行环境及监控需求,提出一种监控框架。该框架以事件计算建模行为规约,在无法对构件服务进行插装的情况下实现对复合服务的有效监控。

A RUNTIME MONITORING METHOD FOR COMPOSITE WEB SERVICES

With the rapid development of computer technology,software is facing increasingly severe dependability requirements.As a result,runtime monitoring has attracted wide public concern as an important way to ensure software dependability.In this paper we analyse and summarise the basic problem and method of traditional runtime monitoring technology,present a basic view in regard to the runtime monitoring method.Then we propose a monitoring framework for special running environment and monitoring demands the composite Web services encountering.The framework uses the event calculus to model behaviour protocol,and achieves effective monitoring of the composite services in the case of being unable to instrument in component services.
