The HappyFace Project

An efficient administration of computing centres requires sophisticated tools for the monitoring of the local computing infrastructure. The enormous flood of information from different monitoring sources retards the identification of problems and complicates the local administration unnecessarily. The meta-monitoring system "HappyFace" offers elegant mechanisms to collect, process and evaluate all relevant information and to condense it into a simple rating visualisation, reflecting the current status of a computing centre. In this paper, we give an overview of the HappyFace architecture and selected modules.
