SGER: NMI: Grid Usage Sensors and Services

这个SGER提案旨在设计和原型化一个测量和报告网格使用情况的系统和服务。该系统名为GUSS，将跟踪、存档并提供网格环境中的使用和性能数据，以供报告和显示。具体来说，这项工作将提供可视性的Globus工具包启用网格环境中的文件传输。这项工作的动机在很大程度上是需要更好地了解异常，如不成功和成功的重新启动，以及更准确的评估电网的容错能力。访问GUSS服务的建议发生通过网格门户架构的框架。实现计划的目标是服务器端GridFTP，这是目前网格环境中使用的主要文件传输引擎。计划将通过采用Netlogger进行数据传输和存档，利用网格仪器、日志记录和存档方面的现有工作。开发将与正在进行的NMI活动紧密结合，包括GUSS门户组件对门户软件的NMI网格门户存储库的潜在贡献。近期部署的原型GUSS系统，包括一个支持GUSS的GridFTP，是针对Teragrid和PPDG的。SGER的一部分探讨了该提案所称的与在存在隐私和安全问题的情况下监控和报告用户活动有关的社会学问题。

This SGER proposal seeks to design and prototype a system and service for measuring and reporting grid usage. The system, called GUSS, will track, archive, and make available for reporting and display usage and performance data in a grid environment. Specifically, the work will provide visibility into file transfers in Globus Toolkit enabled grid environments. The work is motivated in large part by the need for better visibility into exceptions, such as unsuccessful and successful restarts, and a more accurate assessment of fault tolerance in grids. Access to GUSS services is proposed to occur through the framework of the Grid Portal architecture. Implementation plans target server-side GridFTP, the main file transfer engine in use in grid environments today. Plans will leverage existing work in grid instrumentation, logging, and archiving by adopting Netlogger for data transmission and archiving. Development will be tightly integrated with ongoing NMI activities, including potential contributions of GUSS portlets into the NMI Grid Portal repository of portal software. Near-term deployment of the prototype GUSS system, including a GUSS-enabled GridFTP, is targeted for Teragrid and PPDG. One part of the SGER explores what the proposal calls sociological issues relating to the monitoring and reporting of user activities in the presence of privacy and security concerns.
