Operational Data Analytics in practice: Experiences from design to deployment in production HPC environments

(ODA) techniques, which extract knowledge from the massive amounts of data produced by monitoring systems and use it for enacting control over system knobs, or for aiding administrators through visualization. As ODA is a multi-faceted problem, much research effort has gone into finding solutions to its separate aspects: however, comprehensive solutions to enable production use of ODA are still rare, while accounts of ODA experiences and the associated challenges are even harder to come across.In this work we aim to bridge the gap between ODA research and production use by presenting our own experiences, associated with proactive control of warm-water
