The architectural design for the logging, monitoring and alarm systems for the ASTRI mini-array

The ASTRI (Astrofisica con Specchi a Tecnologia Replicante) Mini-Array project is a wide international effort led by the Italian National Institute for Astrophysics to build and operate an array of nine ASTRI telescopes*. The Mini-Array is sensitive in the energy range 1-200 TeV with an angular resolution of a few arcmin and will be operated as an instrument dedicated to very high-energy gamma ray astrophysics.
Large volumes of monitoring and logging data result from the operation of such a large scale astrophysical infrastructure. In the last few years several “Big Data” technologies have been developed to deal with a huge amount of data especially in the Internet of Things (IoT) framework.
We present the logging, monitoring and alarm system architecture for the ASTRI Mini-Array in order to improve the operations of the telescope facility. A prototype was designed and built employing the latest software tools and concepts coming from Big Data and Internet of Things and a particular emphasis has been given to meet quality requirements such as performance, scalability and availability.
