Unified service level monitoring using CIM

This paper contributes to service level management of complex Web-based e-business environments using WBEM/CIM. Such e-business environments usually consist of Web servers and Web containers to realize client access, and EJB containers or CORBA components for modeling the application business logic. Since the DMTF does not define a model providing a unified view upon such complex environments, the definition of a management information model is the core part of the work presented. Currently, the information model mainly focuses on performance aspects, like application response times, which are integral part of many SLAs. The paper also presents a framework that was developed to efficiently implement the information model. The framework increases the portability of CIM providers, which are responsible for retrieving management information, between different CIMOMs by providing an abstraction layer. In addition, the framework simplifies the development of providers by offering support for caching etc.
