Managing polling adaptability in a CIM/WBEM infrastructure

Nowadays, new management paradigms are based on more and more autonomous and decentralized decision-making. Thus, an adaptive management of the volume and the quantity of information supplied by the monitorisng mechanisms is essential. This paper presents works in progress carried out to facilitate the automation of the monitoring processes adaptation. It focuses on a control-oriented characterization of polling mechanisms that leads to the specification of a set of parameters affecting the polling execution, and to a formal representation of the polling mechanism and of the monitoring adaptability. An “adaptable poller” module, based on a unified algorithm which is able to consider, initially and at run-time, the variations of the polling parameters, has been designed, developed and tested in a CIM/WBEM environment. This module offers a polling service that can be controlled by any business management component that would wish to act both on the quality of the information collected and on the performances of the polling mechanism itself.
