基于中间件的运行时监测与分析框架

Middleware Based Runtime Monitoring and Analyzing Framework

运行时刻软件的监测与分析不仅可以提高软件质量，也是软件自适应性的基础．本文提出了基于模式的声明式约束描述方法，以此为基础，在J2EE中间件PKUAS上开发了运行时监测与分析框架，其最大的特点是探针的灵活部署和监测面向业务逻辑的约束．最后，阐述了框架的实现和相关实验的效果．

Runtime software monitoring and analyzing is not only the approach to improve the quality of software, but also the basis of adaptive software. This paper proposes a pattern-based declarative approach to specify constraints. Based on this approach we implemented a runtime monitoring and analyzing framework on J2EE middleware PKUAS. The most special points of the framework are the flexibility of deploying probes and business logic oriented monitoring. In the end, the paper describes the implementation details and evaluation result of the framework.
