Architectural design and prototype for the logging, monitoring, and alarm system for the ASTRI mini-array

Large volumes of monitoring and logging data result from the operation of a large scale astrophysical observatory. In the last few years several “Big Data” technologies have been developed to deal with such volumes of data especially in the Internet of Things (IoT) framework. We present the logging, monitoring and alarm system architecture for the ASTRI Mini-Array aimed at supporting the analysis of scientific data and improving the operational activities of the telescope facility . A prototype was designed and built considering the latest software tools and concepts coming from Big Data and IoT and a particular relevance has been given in satisfying quality requirements such as performance, scalability and availability.
