Issues about the Integration of Passive and Active Monitoring for Grid Networks

SUMMARY In this paper we discuss the issues arising with the integration of passive and active monitoring techniques for Grid network infrastructure monitoring. Our proposal is related to the monitoring information production and publication. Initially, we present the context of our work within the Grid world. We enlist the range of different techniques to perform measurements and obtain monitoring data. We propose a number of interesting performance metrics of the quality of the Grid infrastructure connectivity, and the related passive and active monitoring techniques that are required in order to obtain these metrics
