监控系统中获取进程信息的算法实现

在现代空管系统中进行网络管理时，监视、统计各席位主机进程信息至关重要．因此，作者在网络监控中加入了获取进程信息的功能，在一定时间间隔收集被管主机的所有进程信息，以达到性能管理的目的．介绍了算法实现所需的一些基本概念，然后着重阐述进程信息获取算法及实现．算法中充分考虑了Unix系统特有的虚拟文件系统特点，以及进程状态的动态性．监测结果表明，算法具有较强的透明性和鲁棒性，获取数据误差小．

Implementation of Algorithm to Acquire Process Information in Monitor and Control System

It is important to monitor process information in network management of ATC. Therefore, an module to acquire the process information is put into in the network monitor and control system, which get process information of each host in the network during a certain time in order to supervise device performance. Firstly, introduces some fundamental concepts which the arithmetic is based on. Then, it describes the arithmetic in detail. The arithmetic makes full use of VFS (Virtual File System) of Unix and the dynamic characteristic of process so that it is transparent and robust and the testing results have only negligible error.
