基于公共信息模型的分布式系统业务管理

为了管理Web服务所依赖的底层资源，提出了不同体系结构管理集成的通用业务管理机制．该机制将业务管理的服务级协定(SLA)监视过程分解成配置服务、测量服务、条件评估服务和管理服务，并给出实现服务的最佳方案．建立了SLA参数与资源度量的映射，将SLA从Web服务环境配置到传统管理构架的公共信息模型对象管理器(CIMOM)，并将CIMOM的测量数据传回给Web服务，达到2种体系结构间管理的互操作性．通过主动资源代理，自觉请求检索新度量和计算SLA参数，无需外部触发，有效降低了系统的开销．仿真实验表明，该机制可提高分布式系统的业务监控能力。

Service Management of Distributed Systems Based on Common Information Model

In order to effectively manage the underlying resources that Web services rely on, a generic service management mechanism which can integrate Web services-based management with traditional management architectures CIM (common information model) was proposed. The SLA(service level agreement) monitoring process of service management was decomposed into deployment service, measurement service, condition evaluation service, and management service. In addition, the best solution for carrying out these services was given. To achieve management interoperability between Web services and CIM, the mapping between SLA parameters and resource metrics was created. SLA from Web services environment was configurated as CIM object manager (CIMOM) and measurements from CIMOM was transmitted back to the Web service. Furthermore, the active resource agent which can retrieve metric values automatically from managed resources was created, and SLA parameters without being triggered by an external client was calculated, thus the overhead was reduced remarkably. The simulation results show that the mechanism can improve the capability of service monitor and management in distributed systems.
