Abstract

The Cherenkov Telescope Array Observatory (CTAO) embodies the next phase of ground-based gamma-ray astronomy, engineered to function in the age of multimessenger astronomy. This observatory consists of two arrays, accommodating a collective count of more than 60 Cherenkov telescopes. These telescopes are strategically positioned in both the Northern hemisphere on La Palma Island, Spain, and the Southern hemisphere at Paranal, Chile. CTAO integrates a diverse array of telescope designs and scientific instruments, all collaboratively working to achieve unmatched sensitivity and energy coverage. This collective effort aims to advance the exploration of transient phenomena within the GeV-TeV range. This paper delineates the ongoing development of the monitoring, logging, and alarm subsystems within the Array Control and Data Acquisition System (ACADA) for the CTAO. The Monitoring System (MON) is tasked with overseeing and logging the overall conditions of the array. It has the capability to acquire the fundamental data required to enable predictive maintenance to minimize system downtime. The MON provides an unified tool for monitoring data items from telescopes and calibration instruments at CTAO sites, ensuring immediate availability for operators and facilitating quick-look quality checks. Meanwhile, the Array Alarm System (AAS) collects, filters, and exposes alarms originating from ACADA processes and array elements, thereby enhancing observational efficiency. This paper outlines the MON and AAS, including the technological implementation choices.
