Abstract:

In ATC system,in order to ensure that the whole system operates for a long time without trouble,system monitoring 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.

Key words: ATC system, monitoring agent, SNMP, performance analysis
