摘要： 在现有网格监控系统中，单个目录服务因存储数据量过大而导致查询效率低下，而采用分布式的目录结构又会使系统相对比较松散。该文提出一种按域划分基础上的分层目录服务体系结构。实验证明，在大规模的应用中，该系统的效率优于传统的单个目录服务的监控系统，符合网格环境的特点。该系统以域为单位进行网格节点的信息组织，符合单位或机构的管理模式，具有较强的可扩展性。

Abstract: Single directory services of existing grid monitoring system has low querying efficiency caused by huge date storage, while much nesting will affect querying performance, sothis paper proposes a layered directory services system structure which is carving up on fields. According to experiment, it shows that the system structure satisfies the performance characteristic of grid environments completely, and it precedes traditional monitoring system of single directory services in large-scale application. Organizing messages of grid nodes on field fits manage mode of actual command department or institution, so it has strong expansibility.

Key words: grid, grid source monitoring system, resources monitoring
