A hardware complex of sensors, controllers of connected devices, and monitoring system controllers collects and initially processes the state of key engineering systems of the data processing center (primarily power supply and refrigeration systems), climate parameters in the room, and also adds information about physical security (video surveillance, monitoring the status of doors and etc.). At the software level, this information is collected, processed and visualized using software that is deployed in the cloud or software that is deployed on a local server. Information analysis, planning, modeling of changes and remote monitoring of the condition of key engineering systems of the data processing center are also provided.
