1、安装所需组件

yum install perl perl-develperl-CPANbc net-snmpd net-snmp-utils-y

perl -MCPAN -eshell &cpan> install Bundle::LWP

编译安装nrpe（参考教程：http://2860664.blog.51cto.com/2850664/1559056）


以下是被监控端设置

2、下载check_traffic.s脚本

下载地址：https://codeload.github.com/cloved/check_traffic/zip/v1.3.11

解压文件后，上传check_traffic.sh到/usr/local/nagios/libexec

chmod +xcheck_traffic.sh

chown nagios.nagcmdcheck_traffic.sh

3、设置snmp参数

vi /etc/snmp/snmpd.conf

com2secnotConfigUser被监控端IPpublicgroupnotConfigGroupv1notConfigUsergroupnotConfigGroupv2cnotConfigUserviewsystemviewincluded.1.3.6.1.2.1.1viewsystemviewincluded.1.3.6.1.2.1.25.1.1accessnotConfigGroup""anynoauthexactallnonenoneviewallincluded.180syslocationUnknown(edit/etc/snmp/snmpd.conf)syscontactRoot<root@localhost>(configure/etc/snmp/snmp.local.conf)

service snmpd start

chkconfig snmpd on

4、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 -B

OK - 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[check_traffic]=/usr/local/nagios/libexec/check_traffic.sh-V 2c -C public -H192.168.1.247-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.cfg

6、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

报错信息

7、nagios服务器报错
