Monitoring performance in distributed systems

Abstract

Continuous monitoring of computer network performance is probably the only solution which allows prompt identification of anomalous functioning conditions and provides knowledge of parameters on which to base recovery interventions. A number of tools for performance management already exist, but their effectiveness is limited as they are essentially inserted inside owner network management solutions. In this paper we describe the realization of PMt, a platform for the development of performance management applications for the control and real-time management of a heterogeneous computer network. PMt uses an object-oriented approach in managing the various elements in the distributed system, and defines a methodology for the design of applications to monitor performance. The methodology is mainly destined for use on distributed systems, and provides the user with a set of tools and services that can be used to develop management applications.
