  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).
