In last few years extraordinarily strong trend of rapid development of dedicated telecommunications networks, mostly specialized Information Systems, is observed. Still growing number of users as well as continuously rising needs and requirements regarding business services delivered by these systems, implies increasing complexity of solutions being build. Therefore unfortunately at the same time in these implementations a matter of ?desired? dependability level turns out to be extremely important. These problems bring necessity for introducing new methods and tools for managing such structures. Hence, it becomes urgent to develop innovative techniques of modelling and monitoring of networks. This paper describes the subject of using multilevel distributed agent-based architecture for monitoring purposes, thus making possible to efficiently gather data which may be useful for building comprehensive view of the whole network in automated way. Model created in this way because of its standardized form may find many applications in further stages of management process, which tends to increase system dependability, e.g. using it as one of an inputs of computer network simulator, etc.
