Site Specific Monitoring from Multiple Information Systems -- The HappyFace Project — Volker Büge¹, •Viktor Mauch¹, Gregory Schott¹, Günter Quast¹, and Artem Trunov² — ¹EKP, Universität Karlsruhe, KIT — ²Forschungszentrum Karlsruhe, KIT

Complex computing systems require sophisticated monitoring tools for an efficient administration of the local infrastructure. Sharing such resources in a grid infrastructure, like the Worldwide LHC Computing Grid (WLCG), goes ahead with a large number of external monitoring systems, offering information on the status of the services of a grid site. A look at the current monitoring applications of the WLCG reveals numerous disadvantages. The huge flood of information, which is provided by many different sources, complicates the identification of errors. Furthermore, the totality of all grid monitoring systems is too uncomfortable to be used. Nearly each monitoring system of the WLCG is designed to store information of all grid sites. The resulting setup of the web interfaces according to own requirements and the high response times unnecessarily handicap a regular site check.

A meta monitoring system with an adaptable configuration for a special site could automatically query the relevant information and provide a fast and comfortable access to all important information for the local administration. This talk will describe such a system, called the HappyFace Project. It is a modular software framework which accesses existing monitoring sources, processes the results and creates a simplified overview of the current operational status of a grid site and its specific services.
