关系网格监控体系结构（R-GMA）
Relational Grid Monitoring Architecture (R-GMA)
摘要：
我们描述的R-GMA（关系网格监测体系结构），它已被开发的欧洲数据网格项目作为一个网格信息和监测系统。它基于GGF的GMA，这是一个简单的消费者-生产者模型。这种实现的特殊优势来自于关系模型的强大功能。我们提供了一个信息的全局视图，就好像每个虚拟组织都有一个大型关系数据库一样。我们提供了许多具有不同特征的不同Producer类型;例如，一些支持信息流。我们还提供组合的消费者/生产者，能够组合信息并重新发布。系统的核心是中介，对于任何查询，都能够找到并连接到最好的生产者。我们已经开发了组件，以允许MDS和R-GMA之间的相互作用的措施。我们使用它来获取有关网格的信息（主要是了解在任何时候有哪些服务可用）和应用程序监视。R-GMA已部署在各种测试平台，我们描述了一些初步的结果和经验，这种部署。
英文摘要：
We describe R-GMA (Relational Grid Monitoring Architecture) which has been developed within the European DataGrid Project as a Grid Information and Monitoring System. Is is based on the GMA from GGF, which is a simple Consumer-Producer model. The special strength of this implementation comes from the power of the relational model. We offer a global view of the information as if each Virtual Organisation had one large relational database. We provide a number of different Producer types with different characteristics; for example some support streaming of information. We also provide combined Consumer/Producers, which are able to combine information and republish it. At the heart of the system is the mediator, which for any query is able to find and connect to the best Producers for the job. We have developed components to allow a measure of inter-working between MDS and R-GMA. We have used it both for information about the grid (primarily to find out about what services are available at any one time) and for application monitoring. R-GMA has been deployed in various testbeds; we describe some preliminary results and experiences of this deployment.
