Distributing this data in near real-time, requires a scalable messaging strategy to ensure optimal performance regardless of the number of systems connected. Internal systems include the MeerKAT Graphical User Interfaces, the MeerKAT Science Data Processing subsystem and the MeerKAT Correlator Beamformer subsystem. External systems include Pulsar Timing User Supplied Equipment, MeerLICHT and the Search for Extraterrestrial Intelligence (SETI). Many more external systems are expected to join MeerKAT in the future. This paper describes the strategy adopted by the Control and Monitoring team to distribute near real-time monitoring and scheduling data at scale. This strategy is implemented using standard web technologies and the publish/subscribe design pattern.
