ULMon - Grid nonitoring from user point of view

Leveraging a complex infrastructure such as the computing Grids requires an appropriate level of monitoring. Since it is a technology in development, the current computing Grid middleware offer very little monitoring capabilities from the users´ point of view. Making the Grid closer to the users requires that the users have deeper insight of what is happening with the computational jobs they submit. In this paper we present a novel tool for monitoring the gLite based Grid infrastructure from the users´ perspective.
