There is however no simple, secure and performant way yet to query large amounts of aggregated historical data. This paper presents an implementation of a tool, able to make massive quantities of pre-indexed historical data stored in ElasticSearch available to a large amount of web-based consumers through asynchronous web protocols. It also presents a simple, Opensocial-based dashboard architecture, that allows users to configure and organize rich data visualizations (based on Highcharts Javascript libraries) and create navigation flows in a responsive mobile-friendly user interface. Such techniques are used at CERN to display interactive reports about the status of the LHC infrastructure (e.g. vacuum or cryogenics installations) and give access to fine-grained historical data stored in the LHC Logging database in a matter of seconds.
