摘要： 提出了开放可扩展的监控信息模型，在Globus MDS4监控系统的基础上，增加信息持久化功能，将监控信息收集服务化，实现了网格数据库性能监控系统——DBMg。实验证明，该系统对被监控数据库性能影响很小，为数据库的故障诊断、性能调整和优化提供了强有力的支持。

Abstract: Based on Globus MDS4 monitoring system, this paper proposes an open and extensible monitoring information model, on which a persistent function is added, service for collected monitoring information is offered, and a grid database performance monitoring system——DBMg is implemented. Experimental results show DBMg is a powerful monitor tool for fault diagnoses, performance adjustment, performance optimization with minimum impact on the database.

Key words: grid, monitoring, database, DBMg
