– Application services are fundamental network components that allow organizations the ability to operate efficiently. It has become essential for organizations to monitor the performance of these critical applications. Traditional network analysis tools, however, cannot cope with the size of today’s network infrastructures and the volume of network data generated. The goal of this paper is to discuss the development of a visualisation system, called AppVis, that uses new information visualisation techniques to enable UPE to effectively visualise the application delay performance of the ITS application implemented on the network. KEYWORDS – Application performance management, application delay metrics, information visualisation.
