在空管系统中,为了确保整体系统能够长时间无故障地运行,监控系统的存在必不可少。监控代理作为监控系统的重要组成部分,需要对空管系统中的相关设备及关键进程的工作状态进行实时地监控。阐述了空管系统中监控代理的基本结构和通信方式,给出了3种不同的方式实现监控代理的功能。其中介绍了使用SNMP获取监控代理信息的方法 ,并借助Net-SNMP软件作为SNMP代理,描述了基于Windows操作系统实现对Net-SNMP软件进行代理功能扩展的开发流程,然后对不同方式的性能进行对比及总结,以达到可以根据不同的应用需求和不同的设备环境有效地选择最佳的方式完成监控的目的。
In the air traffic control system, in order to ensure that the entire system can be trouble-free operation for a long time, the presence of monitoring system is essential. As an important part of the monitoring system, the monitoring agent needs to monitor the working status of related equipment and key processes in the ATC system in real time. The basic structure and communication mode of the monitoring agent in the air traffic control system are expounded. The functions of the monitoring agent are given in 3 different ways. This paper introduces the method of using SNMP to obtain the monitoring agent information. With Net-SNMP software as the SNMP agent, it describes the development process of expanding the Net-SNMP software agent function based on the Windows operating system, and then compares the performance of different ways And summarize, so as to achieve the purpose of effectively selecting the best way to complete the monitoring according to different application requirements and different equipment environments.
