Toward configurable performance monitoring: Introduction to mathematical support for metric representation and instrumentation of the CIM metric model

This research study addresses the design of a QoS & Management-oriented architecture capable of recognizing the specified metrics in order to monitor them dynamically. Particularly, this paper deals with the representation and instrumentation of metrics reflecting the performance and the dynamic characteristics of network resources and services. This study focuses on some recent research projects related to the monitoring of Web Services performance at the application layer. Based on our objectives and evaluation criteria, we identified several lacks such as standards adoption, generic and adaptable architecture. While taking into consideration the integration and interoperability of a wide variety of management protocols, our architecture adopts the Common Information Model (CIM) as an information model. This model is exploited as a mediator to exchange information between the QoS & Management worlds, and the Monitoring world.
