Description

From humble beginnings of a hand-maintained list and a combination of ssh + screen to today, the European Spallation source currently has over 3,400 active IOCs which serve over 11,000,000 PVs. We will describe how we manage configuration for our systems emphasizing traceability, reproducibility, and quality control. We will also show how this allows us to monitor various aspects of our system including host and IOC logs, pv and archival status all from a centralised location. Finally, we will show how we are able to acheive fast updates to production systems as required to address the infamous "2am problem" or even worse, the "who deleted my control system" problem.
