基于SLA的网格监控体系GSLMA及其实验床

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.

Monitoring grid on service level, GSLMA and its test bed

Grid monitoring toolkits was classified into three categories from the point the view of architecture and a novel architecture of grid monitoring, GSLMA(grid service level monitoring architecture) was presented,which was based on SLA(service level agreement). GSLMA was a SOA(service oriented architecture) with high flexibility and scalability. It supported third-party monitoring and could be extended to monitor emerging grid services without much additional programming. 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 service architecture) container, using WSLA(Web service level agreement) to describe the monitoring information and etc.
