In order to improve the effectiveness of remote monitoring of central computer room servers,this paper discusses and proposes a remote monitoring method for central computer room servers based on a portable KVM controller.This method is based on a portable KVM controller to complete the architecture design of server remote monitoring hardware,and based on this,complete the design of server monitoring module,parameter management module,and operation management model.The feasibility and progressiveness of the method proposed in this paper are verified by an example.The experimental results show that the method proposed in this paper can effectively monitor the servers in the central computer room,and the monitoring accuracy is high,which has certain promotion and application value.
