【nagios 三】 nagios被监控端配置

完成了nagios的服务器端的设置后，则需要在被监控主机端做相关设置，设定一些监控参数值。

完整的配置脚本如下：

#!/bin/bash
#auto configure nagios linux client side
#2012-12-05

nagios_dir="/usr/local/nagios"
nagiosrv="192.168.0.50"

function Install_nagios()
{

     chown -R nagios:nagios $nagios_dir

     cd /usr/local/src/nrpe-2.13  #编译安装nrpe包
     ./configure
     make all
     make install-plugin
     make install-daemon
     make install-daemon-config
}

function Set_nagios()
{
     cd $nagios_dir/etc/
     sed -i.bak '/server_address/ s/^#//' nrpe.cfg  #修改主机的nrpe配置文件
     sed -i '/server_address/ s/=.*$/=0.0.0.0/' nrpe.cfg

     sed -i '206acommand[check_swap]=/usr/local/nagios/libexec/check_swap -w 30% -c 10%' nrpe.cfg  #追加监控swap容量的命令

}

{
     kill -9 `cat /var/run/nrpe.pid` > /dev/null 2>&1
     $nagios_dir/bin/nrpe -c $nagios_dir/etc/nrpe.cfg -d
}
