This paper mainly introduces the OpenNMS, an open source software of enterprise-level network management platform, and an implementation of it in the Hunan Provincial Center for Disease Control and Prevention (CDC). We use OpenNMS to realize real-time monitoring of network equipment, servers, and applications in the data center of Hunan Provincial CDC. Especially in the scenario of limited funds, and the lack of SMS gateways and private e-mail servers, network bottlenecks and fault alarms are discovered in a timely manner with minimal cost. HP Data Protector (hereinafter referred to as DP) is an HP's backup software that provides reliable data protection and high accessibility for fast-growing business data. This paper also describes the usage of HP DP's reporting and alerting capabilities, and the HP DP alarm is used as an example to demonstrate the e-mail alarm function of OpenNMS.
