下载最新的check_trafic

cd /usr/local/nagios/libexec/

wget   https://github.com/downloads/cloved/check_traffic/check_traffic_v1.3.7.zip

解压

然后更改所属

chown nagios:nagios check_traffic.sh

执行如下命令查看网卡

/usr/local/nagios/libexec/check_traffic.sh -V 2c -C nagios -H localhost -L

（which: no bc in (/program/system/jdk1.6/bin::/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin)

Can not found command bc in you system PATH: /program/system/jdk1.6/bin::/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin, pleas check it

*****解决办法

yum install bc

）

查看网卡流量：

/usr/local/nagios/libexec//check_traffic.sh -V 2c -C nagios -H localhost -I 2 -w 12,30 -c 15,35 -M –b

vi /usr/local/nagios/etc/nrpe.cfg

command[check_traffic]=/usr/local/nagios/libexec/check_traffic.sh -V 2c -C nagios -H localhost -I 2 -w 12,30 -c 15,35 -M –b

重启xinetd

service xinetd restart

修改

chmod 666 /var/tmp/check_traffic*

主控端添加：

define service{

        use                                         local-service,srv-pnp         ; Name of service template to use

        host_name                             B_CUS_WEB_192.168.0.10

        service_description                check_traffic

        check_command                   check_nrpe!check_traffic
