SCI: NMI DEVELOPMENT: Performance Inside: Performance Monitoring and Diagnosis for NMI Software and Applications

该提案旨在开发软件和工具，以自动管理收集、分析和应用各种性能信息的过程，并在此过程中导致对分布式系统和应用程序的基线性能行为和故障条件的理解。这些工具将支持扩展监视框架的开发，通过使用广泛部署的一组传感器或探针来收集基本数据，从而能够捕获整个环境中的性能数据。这项工作将使传感器易于管理和配置，因此收集的数据量可以根据情况而变化。传感器将能够注册到一个共同的注册表中，以便用户可以轻松地发现和选择与特定应用相关的传感器。将提供其他工具，如归档器和预测服务，以存储性能数据并估计未来的行为。将提供触发服务用于早期故障检测，并提供高级分析工具用于行为诊断。该项目将生产(1)NMI传感器工具包，实现各种简单传感器模板的软件，以便传感器可以轻松地合并到工具、应用程序和其他服务中，向用户提供性能数据；(2)性能支持的NMI软件，各种NMI组件的传感器增强版本（例如，Globus Toolkit的GRAM、GridFTP、RFT、MDS、mpch - g2、OpenSSH、MyProxy）；(3)分布式环境中用于归档、分析和控制性能监测的传感器管理工具、服务和工具；(4)客户端工具（api、库、命令行工具、实用程序），为用户和系统管理员提供简单易懂的性能数据访问。

The proposal seeks to develop software and tools to automate management for the process of collecting, analyzing, and applying diverse performance information, and in so doing lead to the understanding of baseline performance behavior and failure conditions of distributed systems and applications. The tools will support the development of extended monitoring frameworks that enable the capture of performance data across the environment by using a set of sensors, or probes, widely deployed to gather basic data. The work will enable sensors to be managed and configured easily, so that the amount of data collected can be varied according to the situation. Sensors will be able to register into a common registry so that users can easily discover and select the sensors relevant to a specific application. Additional tools, such as archivers and prediction services, will be provided to store performance data and estimate future behaviors. Trigger services will be provided for early fault detection, and higher-level analysis tools for behavioral diagnosis. The project will produce (1) a NMI Sensor Toolkit, software that implements various simple sensor templates so that sensors can easily be incorporated into tools, applications, and other services to provide performance data to users; (2) performance-enabled NMI software, sensor-enhanced versions of various NMI components (e.g., Globus Toolkit's GRAM, GridFTP, RFT, MDS; MPICH-G2; OpenSSH; MyProxy); (3) sensor management tools, services and tools for archiving, analyzing, and controlling performance monitoring in a distributed environment; and (4) client tools (APIs, libraries, command line tools, utilities) that provide users and system administrators with easy and understandable access to performance data.
