空管系统中多种监控代理的实现及性能对比

Achievements and performance comparison of multiple monitoring agents in air traffic control system

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 ATC system, in order to ensure that the whole system operates for a long time without trouble, system moni- toring is essential. The working status of related equipment and key process in ATC system must be monitored in real-time by monitoring agent, which is an important part of monitoring system. Firstly, the basic structure and communication mode of monitoring agent are elatorated, and then three different methods of monitoring function achieving are proposed. SNMP method is introduced to obtain the information of monitoring agent. With Net- SNMP software as an SNMP agent, the development process of Net-SNMP agent extension based on Windows operating system is described. Furthermore, a comparison and summary is made about the performance of these methods. According to different application requirements and equipment environments, the most effective way to complete monitoring function can be selected.
