Monitoring grid on service level, GSLMA and its test bed

摘要: 从体系结构的角度出发,将现有网格监控工具分为3类,对每一类网格监控结构进行了分析 和对比,并提出了一种基于服务级别协定SLA(Service Level Agreement)的网格服务监控体系结构GSLMA(Grid Service Level Monitoring Architecture).GSLMA采用基 于面向服务的体系结构SOA(Service Oriented Architecture)的松散耦合结构,通过动态部 署解决了对新增服务的监控扩展,并提供第三方的监控功能,是一个具有高灵活性和高可伸 缩性的网格监控体系结构.最后,介绍了实现GSLMA实验床中的关键技术,包括:对开放网格 服务体系结构OGSA(Open Grid Service Architecture)容器进行扩展,采用Web服务级别协定WSLA(Web Service Level Agreement)解决被监控服务信息的统一描述等等.Abstract: Grid monitoring toolkits was classified into three categories from the point the view of architecture and a novel architecture of grid monitoring, GSLMA(grid s ervice level monitoring architecture) was presented,which was based on SLA(serv ice level agreement). GSLMA was a SOA(service oriented architecture) with high flexibility and scalability. It supported third-party monitoring and cou ld be extended to monitor emerging grid services without much additional program ming. In the end, several key technologies were introduced in implementation of a test bed of GSLMA, such as: extending functionalities of the OGSA(open grid se rvice architecture) container, using WSLA(Web service level agreement) to descri be the monitoring information and etc.
