Cross-domain operation and maintenance system based on one-way gatekeeper environment

The invention discloses a cross-domain operation and maintenance system based on a one-way gatekeeper environment. The professional management system of each low-security-level sub-network stores themonitored and acquired data into the sub-network system; and the comprehensive operation and maintenance management center of the subnet extracts the state information of the monitored resources, andpushes the state information to the high-security-level core network system through the one-way gatekeeper, so that the operation and maintenance management system of the high-security-level core network performs whole-center resource situation display and alarm display. The system can provide a panoramic data view of center resources, has the characteristics of wider monitoring coverage, more accurate and efficient fault solution, more reasonable resource allocation and the like, and can promote the intelligent and unmanned development of enterprise data center operation and maintenance. 本发明公开了一种基于单向网闸环境的跨域运维系统，各个低密级子
