Abstract: The advantages of SNMP protocol, such as simplicity, wide application and regardless of physical differences between devices, are applied to the operation and maintenance of GNSS reference station. The cloud monitoring platform is designed to monitor and manage devices of different types, manufacturers and models in different physical spaces, which greatly reduces the burden of network administrators in maintaining various devices, and discovers and locates faults at the first time, effectively enhances operational and maintenance capabilities. The cloud monitoring system based on SNMP protocol is deployed in the seismic industry network. Through the technologies such as physical resource virtualization, virtual resource redistribution, and free migration of business systems among multiple servers, the shortcomings of traditional computer rooms such as one service occupying one server and service downtime meaning business interruption are really abandoned.
