With the completion of the Tenth Five-Year Plan, Earthquake Administration of Hubei Province has finished the data sharing with China Earthquake Administration and neighboring provinces. Unsatisfied with the effect of applying commercial network management softwares to monitor the whole earthquake network, the authors made in-depth research on the open source monitoring software “Nagios”, and established an earthquake network monitoring system to perform visualized surveillance on network equipments and their services. In this paper, we first describe the structure of the entire monitoring system, and then introduce the implementation of the system and the innovation of alarm function and finally discuss the existing problems.
