Abstract
The ASTRI SST-2M telescope is a robotic end-to-end prototype, installed on Mount Etna (Italy) and proposed for the Small Size class of telescopes of the future Cherenkov Telescope Array (CTA). The ASTRI prototype is currently operative and it is undergoing the scientific verification stages. In the next future a first set of nine ASTRI telescopes is foreseen for the early implementation of the CTA southern site. In this contribution we present the general design of the monitoring system for the Information and Communication Technology (ICT) infrastructure of the ASTRI SST-2M prototype. The ASTRI ICT monitoring system is composed by specific custom tools which interface the ICT device, through the Open Platform Communication Unified Architecture (OPC-UA) protocol, to the Alma Common Software (ACS), which is the high-level framework used to operate the ASTRI SST-2M prototype. The main purpose of these tools is to convert the Internet Control Message Protocol (ICMP) and Simple Network Management Protocol (SNMP), used in the ICT devices, into the OPC-UA protocol, through the implementation of an appropriate OPC-UA server. This server interacts with an OPC-UA client implemented as ACS components, which are able to provide all the ICT monitoring parameters, through the ACS notification channel and sends alerts to the central console of the ASTRI SST2M telescope prototype. ICT monitoring data are also saved into the ACS Telescope Monitor Communication Data Base (TMCDB), like those of the other telescope subsystems. The same approach has been proposed for the monitoring of the CTA on-site ICT infrastructures. © 2018 SPIE.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
