摘要
信息服务系统在社会中的地位越来越重要,需要提高其连续稳定运行的能力。但由于其依赖组件众多、规模和复杂度日益提高,监控和处置难度大。本文从外部监控角度出发,以应用组件运行状态为核心进行了数学方法分析,并以实践角度对其进行处理,提出了一个是实用化的模型,并得到了软件实现,取得预期效果。同时对该产品应用于国家科学技术文献服务系统的效果做出介绍。
Information services are very important in current. Theirs continuous running and stability should be improved. However, technology and component of information service system are more and more complex. Monitoring and maintenance are difficult. This article from the perspective of an external monitor, split application into component, mathematical analysis the application components running state, by practical point of view, in the article, a practical algorithm and a model and has been implemented and modified, and a software base the model achieve the desired effect. At the same time, the SMONS System engineer practice and effect in NSTL also be introduced.
