nagios监控linux网卡流量（check_traffic.sh）
1、安装所需组件 yum install perl perl-devel perl-CPAN bc snmpd -y perl -MCPAN -eshell& cpan> install Bundle::LWP 编译安装nrpe（参考教程：http://2860664.blog./2850664/1559056）以下是被监控端设置2、下载check_nginx_status.pl脚本 下载地址：https://github.com/cloved/check_traffic/archive/v1.3.11.zip 解压文件后，上传check_traffic.sh到/usr/local/nagios/libexec chmod +x check_traffic.sh chown nagios.nagcmd check_traffic.sh3、设置snmp参数 vi /etc/snmp/snmpd.conf

service snmpd startchkconfig snmpd on4、在被监控端测试脚本 cd /usr/local/nagios/libexec ./check_traffic.sh -V 2c -C public -H 192.168.1.247 -I 2 -w 1200,1500 -c 1700,1800 -K -BOK - The Traffic In is 0.72KB, Out is 0.60KB, Total is 1.32KB. The Check Interval is 43s |In=0.72KB;1200;1700;0;0 Out=0.60KB;1500;1800;0;0 Total=1.32KB;2700;3500;0;0 Interval=43s;1200;1800;0;0 其中红色为被监控端的IP地址。4、vi /usr/local/nagios/etc/nrpe.cfg添加command=/usr/local/nagios/libexec/check_traffic.sh -V 2c -C public -H 192.168.1.247 -I 2 -w 1200,1500 -c 1700,1800 -K -B
以下是nagios主机的设置5、服务器端测试/usr/local/nagios/libexec/check_nrpe -H 192.168.1.247 -c check_traffic
OK - The Traffic In is 0.48KB, Out is 0.11KB, Total is 0.59KB. The Check Interval is 28s |In=0.48KB;1200;1700;0;0 Out=0.11KB;1500;1800;0;0 Total=0.59KB;2700;3500;0;0 Interval=28s;1200;1800;0;0
vi /usr/local/nagios/etc/nagios.cfg添加
cfg_file=/usr/local/nagios/etc/objects/nginx.cfg6、touch /usr/local/nagios/etc/objects/nginx.cfg vi /usr/local/nagios/etc/objects/nginx.cfg（注意修改被监控端的IP）内容如下****************************************我是分割线************************************
