此脚本参考了Nagios的官方文档https://exchange.nagios.org/并其进行了代码精简和移值,原代码是运行在ksh下面的,定义数组的方式跟bash还是有区别的:另外,为了反映CPU的繁忙程度,特的抓取了vmstart命令中的平均值并将其打印出来.为了方便大家下载,特的将其收录进了我的github中. #!/bin/bash # CPU Utilization Statistics plugin for Nagios IOSTAT="/usr/bin/iostat"

监控之Nagios

NAGIOS Nagios是一款开源的免费网络监视工具,能有效监控Windows.Linux和Unix的主机状态,交换机路由器等网络设置,打印机等.在系统或服务状态异常时发出邮件或短信报警第一时间通知网站运维人员,在状态恢复后发出正常的邮件或短信通知. 一.Nagios概述 1.简介 Nagios是插件式的结构,它本身没有任何监控功能,所有的监控都是通过插件进行的,因此其是高度模块化和富有弹性的.Nagios监控的对象可分为两类:主机和服务.主机通常指的是物理主机,如服务器.路由器.工作站和打印

1.NRPE介绍 NRPE是Nagios的一个功能扩展,它可在远程Linux/Unix主机上执行插件程序.通过在远程服务器上安装NRPE插件及Nagios插件程序来向Nagios监控平台提供该服务器的本地情况,如CPU负载,内存使用,磁盘使用等.这里将Nagios监控端称为Nagios服务器端,而将远程被监控的主机称为Nagios客户端. Nagios监控远程主机的方法有多种,其方式包括SNMP,NRPE,SSH,NCSA等.这里介绍其通过NRPE监控远程Linux主机的方式. NRPE(Nag

Nagios利用NRPE监控Linux主机（3）

一.利用NRPE监控远程Linux的"本地信息" 上面已经对远程Linux 主机是否存活做了监控,而判断远程机器是否存活,我们可以使用ping 工具对其监测.还有一些远程主机服务,例如ftp.ssh.http,都是对外开放的服务,即使不用Nagios,我们也可以试的出来,随便找一台机器看能不能访问这些服务就行了.但是对于像磁盘容量,cpu负载这样的"本地信息",Nagios只能监测自己所在的主机,而对其他的机器则显得有点无能为力.毕竟没得到被控主机的适当权限是不可能
