R-GMA：部署后的第一批结果
R-GMA: First results after deployment
摘要：
我们描述的R-GMA（关系网格监测体系结构），这是正在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。我们提供了信息的全局视图，就好像每个VO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。我们还提供消费者/生产者组合，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来完成工作。我们能够调用MDS信息提供者脚本，并通过R-GMA发布结果信息，此外还拥有一些我们自己的传感器。API允许用户为将来可能需要的任何应用程序部署监控和信息服务。我们使用它来获取有关网格的信息（主要是查找在任何时候可用的服务）和应用程序监视。R-GMA已经在网格测试平台上进行了部署，我们描述了这种部署的结果和经验。
英文摘要：
We describe R-GMA (Relational Grid Monitoring Architecture) which is being developed within the European DataGrid Project as an 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 VO 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 to do the job. We are able to invoke MDS info-provider scripts and publish the resulting information via R-GMA in addition to having some of our own sensors. APIs are available which allow the user to deploy monitoring and information services for any application that may be needed in the future. We have used it both for information about the grid (primarily to find what services are available at any one time) and for application monitoring. R-GMA has been deployed in Grid testbeds, we describe the results and experiences of this deployment.
