分布式代理技术在监控系统中的应用

Application of Distributed Agent Technology to the Monitoring System

集中式监控模型具有简单高效的特点,特别适合对小规模被监控系统的监控,但集中式监控模型在可靠性方面具有明显的缺陷和不足。针对小规模被监控系统,提出了通过在集中式监控模型中引入分布式机制达到提高监控系统可靠性的思想,同时,提出了适合这一特定模型的选举算法、负责均衡算法、负载指标评估模型,并对负载指标进行了量化。对上述模型和算法进行了详细的阐述,对模型和算法的正确性、性能和可靠性进行了分析。

Centralized monitor model is simple and effective, especially for the monitor of small type, but this model has obvious shortcomings on reliability. For monitor system in small type, this paper puts forward an idea to improve reliabilty of the monitoring system. The special model method of the election, the method of balanced duty and loading standard evaluating model and quantified the loading standard for this special model are proposed. This paper describes the models and algorithms, and analyzes the correctness ,performance and reliability of the models and algorithms.
