摘要: 网格监控系统对于保障网格系统正常运转极为重要,是近年来网格研究领域的热点之一。以GMA为基础,提出了一种基于移动代理的网格监控架构(MA-GMA),将基于网格资源有效期的缓存机制与智能性、移动性、自治性等移动代理的特征注入当前的OGSA标准,构造了一个动态的、可扩展的网格监控系统。通过它网格系统的开发者和管理者可以及时发现网格故障根源,分析系统性能瓶颈,为修复和改善系统性能提供依据,使网格系统的服务质量得到可靠保障。

Abstract: The grid monitor system is very important in the grid environment. Based on traditional GMA, this paper puts forward a mobile agent based grid monitor architecture (MA-GMA). The grid monitor architecture is designed based on the features of open grid service architecture (OGSA) standard with the cache mechanism based on period of validity of grid resources, and the intelligence, mobility characteristic of mobile agent is merged into current OGSA, constructing a dynamic and extensible monitor system to ensure the quality of grid service. In the grid environment, it can be used to discover unknown performance problems, find out the root failure in time, analyze the system performance bottleneck, resume and adjust the system in shortest time.

Key words: grid monitor, mobile agent, grid monitor architecture (GMA), grid computing
