【摘要】：开源网络管理软件以其成本低廉，安装简单的优点受到越来越多用户的关注，但开源网络管理软件通常存在使用平台受限，功能不足，缺乏技术支持等缺点。因此，对开源网络管理软件及其改进展开研究具有重要的意义。通过对当前网络管理解决方案进行调研和对比，选取应用广泛的开源网络管理软件Nagios展开研究，设计和实现了一个基于代理的开源网络管理平台。针对Nagios无法应用于嵌入式环境的问题，通过借助嵌入式下移植技术，将Nagios提供的开源代理软件NRPE移植到嵌入式环境下，实现了系统对嵌入式设备的有效监控和管理；通过为系统添加环形数据库，解决了系统缺乏历史数据统计功能的问题，并借助PHP技术，为系统增加图形界面显示接口，使用户管理界面更加直观，友好，便于理解；针对用户实际需要，为系统提供灵活的监控脚本定制功能，，实现了对网络管理系统功能的灵活扩充。论文对所设计的基于代理的网络管理系统进行了功能性测试、可靠性测试和高效性测试，测试结果表明：系统实现了对被监控设备的实时监控和管理的功能，对网络环境变化适应性高，系统响应时间快，系统具有较高的可靠性和高效性，符合用户需求。
[Abstract]:Open source network management software is concerned by more and more users because of its low cost and simple installation. However, open source network management software usually has some disadvantages, such as limited use of platform, insufficient function, lack of technical support, etc. It is of great significance to study the open source network management software and its improvement. Through the investigation and comparison of the current network management solutions, the open source network management software Nagios, which is widely used, is selected to carry out the research. An open source network management platform based on agent is designed and implemented. Aiming at the problem that Nagios can not be applied to embedded environment, the open source agent software NRPE provided by Nagios is transplanted to embedded environment by means of porting technology under embedded environment. The system realizes the effective monitoring and management of embedded devices, solves the problem that the system lacks the statistical function of historical data by adding ring database to the system, and adds the graphical interface display interface to the system with the help of PHP technology. It makes the user management interface more intuitive, friendly, easy to understand, according to the actual needs of users, provides the system with flexible monitoring script customization function, and realizes the flexible expansion of the network management system function. In this paper, the function test, reliability test and efficiency test of the network management system based on agent are carried out. The test results show that the system realizes the function of real-time monitoring and management of the monitored equipment. It has high adaptability to network environment, fast response time, high reliability and efficiency, and meets the needs of users.
