基于web的智能网管系统设计与实现

Design and implementation of intelligent network management system based on web

将简单网络管理协议(SNMP)的思想、NetF low技术、PHP多线程技术融入到网络性能监测系统中,通过对性能数据的采集、存储及分析,设计并开发了一套智能化网管系统。系统采用PHP语言开发,分为数据采集、性能数据库、数据分析及处理、数据显示、阈值设定与警告及用户管理6大模块,不同的模块实现不同的功能。数据采集程序采用了多线程机制对性能数据进行采集,多线程采集各种性能数据,允许一个程序同时有效地执行多个任务,既增强了程序的功能,又提高了程序的性能。数据分析模块主要负责采集端口组、TCP/IP组、UDP组的数据,并结合相关公式就可以计算出我们所需要的实时和历史数据性能指标值。信息显示模块按条件查询方式将端口组、IP组、TCP组、UDP组的性能指标显示出来。实际应用证明,该系统能够监控网络的实时变化,并将异常及时地通过邮件、短信等方式反馈给网络管理员,达到了预期目的。

SNMP protocol,NetFlow technology,multi-threading technology of PHP are introduced into performance monitoring system in this paper.A set of intelligent network monitoring system is designed and developed by collecting,storing and analyzing performance data.PHP language is used to develop the system.It is divided into six modules,such as data acquisition,performance databases,data analysis and processing,as well as data display,threshold settings and warnings and user management.Different modules achieve different functions.Data acquisition program uses multi-threading mechanism to collect a variety of performance data and allows the program to effectively perform multiple tasks simultaneously,so that it not only enhances the program＇s function but also improves the performance of the program.Data analysis module is mainly responsible for collecting data from the port group,TCP/IP group,UDP group and other groups,and combined with the relevant formulas,the real-time and historical data that we need can be calculated.Information display module displays performance of the port group,IP group,TCP group,UDP group and other groups according to the conditions-search ways.Practical application shows that the system has achieved the expected goal by making overall performance more reasonable and improving the efficiency of operation of the campus network greatly through real-time monitoring of performance data,and also reporting the exception to the network manager timely.
