文档介绍：I 摘要大型企业和学校的 IT信息系统,其规模往往非常庞大,服务器总数量可以达到1000-3000 台之多,在日常的运行维护工作中,对这些服务器的运行情况进行监控和管理就是非常具有挑战性的工作。而高可用系统采用负载均衡等方式将故障节点对用户进行自动屏蔽,这种设计就要求监控系统必须及时发现故障点并通知处理。而Nagios 是一个基于 Linux 平台的通用计算机服务监控系统。其具有松散藕合、跨平台、接口标准、高扩展性、可基于 HTTP 协议灵活访问等特点。本课题立足于洛阳理工学院西区校园网,以开源网络监控软件nagio s为基础, 搭建校园网络监控系统。通过对开源网络监控软件 nagios 的二次开发,实现可以满足自身校园网需求的网络监控系统。详细分析了 nagios 的架构原理、工作流程、强大报警和插件扩展方式的同时,也丰富了 nagios 的绘图效果,在原有的邮件报警基础之上,增加了飞信报警、声音报警功能,并且对主机和服务状态进行更直观的监控。关键词: 通用,网络监控,监控利器 nagios ,报警 II D ESIGN AND IMPLEMENTATION BASED ON WORK MONITORING MANAGEMENT SYSTERM ABSTRACT Large enterprises and campus often has a large-scale IT information system, it maybe have 1000 to3000 servers. It's a very challenging work to monitor and manage these servers in daily operation and maintenance. High Availability system use load balance to shield the failed node automatically, this design require monitoring system must detect failures automatically. Nagios isa Linux-based general-puter service monitoring system. It has loosely coupled, cross-platform, standard interface, highly scalable, flexible access via HITTP protocol Features. Based on west of luoyang institute of technology work, based on the open work monitoring software nagios, build work monitoring system. Through the open work monitoring software nagios of secondary development, can meet the demand of work of their work monitoring system. In detailed analysis of the principle of the architecture of nagios, work process and at the same time, the way ofa powerful plug-in extension also enriched the nagios alarm way, based on the original email alarm, increased the fetion alarm, voice alarm function , and the work traffic state more intuitive monitoring. KEY WORDS: General , network monitoring , monitor Nagios , alarming III 目录前言............................................................................................................ 1 第1章绪论................................................................................................. 3 论文选题背景...........
