Networked monitoring of multiple computer rooms has the following characteristics: Firstly, it spreads all over the district/ city/ province, and the computer rooms are scattered and numerous. Secondly, the number of operation and maintenance personnel is limited and centralized operation and maintenance management is difficult. Thirdly, the equipment operation environment, daily inspection and maintenance in each machine room cannot be effectively guaranteed, so centralized monitoring of each machine room is urgently needed. In response to these problems, a networked centralized monitoring and control system of computer room has been built to realize the networked monitoring of all computer rooms distributed in several provinces, cities and regions, and achieve centralized display, management and alarm. On top of this, managers at all levels can view and manage the operation state of the networked rooms in different places according to their authority, so as to reduce manual inspection, workload and maintenance cost, shorten maintenance response time and reduce repeated failures.
