The ASTRI (Astrofisica con Specchi a Tecnologia Replicante Italiana) Mini-Array (MA) project is
an international collaboration led by the Italian National Institute for Astrophysics (INAF). ASTRI
MA is composed of nine Cherenkov telescopes operating in the energy range 1-100 TeV, and it
aims to study very high-energy gamma ray astrophysics and optical intensity interferometry of
bright stars. ASTRI MA is currently under construction, and will be installed at the site of the
Teide Observatory in Tenerife (Spain). The hardware and software system that is responsible of
monitoring and controlling all the operations carried out at the ASTRI MA site is the Supervision
Control and Data Acquisition (SCADA). The LOgging UnifieD (LOUD) subsystem is one of the
main components of SCADA. It provides the service responsible for collecting, filtering, exposing and storing log events collected by all the array elements (telescopes, LIDAR, devices, etc.). In this paper, we present the LOUD architecture and the software stack explicitly designed for distributed computing environments exploiting Internet of Things technologies (IoT).
