  In complex operational environments, monitoring and control systems are asked to satisfy ever more stringent requirements. In addition to reliability, the availability of the system has become crucial to accommodate for tight planning schedules and increased dependencies to other systems. In this context, adapting a monitoring system to changes in its environment and meeting requests for new functionalities are increasingly challenging. Combining maintainability and high-availability within a portable architecture is the focus of this work. To meet these increased requirements, we present a new modular system developed at CERN. Using the experience gained from previous implementations, the new platform uses a multi-server architecture to allow running patches and updates to the application without affecting its availability. The data acquisition can also be reconfigured without any downtime or potential data loss. The modular architecture builds on a core system that aims to be reusable for multiple monitoring scenarios, while keeping each instance as lightweight as possible. Both for cost and future maintenance concerns, open and customizable technologies have been preferred.
