基于SLA的网格监控体系GSLMA及其实验床

Monitoring grid on service level, GSLMA and its test bed

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(ServiceLevelAgreement)的网格服务监控体系结构GSLMA(GridServiceLevelMonitoringArchitec ture) .GSLMA采用基于面向服务的体系结构SOA(ServiceOrientedArchitecture)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(OpenGridServiceArchi tecture)容器进行扩展 ,采用Web服务级别协定WSLA(WebServiceLevelAgreement)解决被监控服务信息的统一描述等等 .

Grid monitoring toolkits was classified into three categories from the point of 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 and using WSLA (Web service level agreement) to describe the monitoring information.
