本文提出了一种针对工作流的系统监控框架.该框架在模型层面赋予了用户更灵活的表达方式,在实例化的运行层面提供了动态的指标计算和具体的实施,既能实时监控系统运行状况,又能监控系统上下文环境,从而使得软件系统能够更好的满足用户需求的变化以及运行环境的变更.
We proposed an system monitoring model of self-adaptive system based on our previous work,which gives users more flexibility in expressing requirements on the model level,provides dynamic QoS value calculation and implementation at run time,and can both monitors operating status of system in real-time and monitor the context of the system,allowing software systems to better meet users' changing needs,and the operating environment changes.
