以下介紹如何裝設 mrtg 監測 eth0 的流量

yum -y install net-snmp

vi /etc/snmp/snmpd.conf

com2sec local localhost public
com2sec mynetwork 192.168.1.0/24 public
group MyRWGroup v1 local
group MyROGroup v1 mynetwork
view all included .1.3.6.1.2.1.1 80
access MyROGroup "" any noauth 0 all none none
access MyRWGroup "" any noauth 0 all all all
syslocation Fedora Core 6

syscontact someone <someone@mail.com.tw>

chkconfig snmpd on

 service snmpd start

yum -y install mrtg

mkdir /home/WWW/www/mrtg #或者其他你要產生mrtg統計檔案的地方

 cfgmaker --global 'WorkDir: /home/WWW/www/mrtg' \
> --global 'Options[_]: bits,growright' \
> -global 'Language: big5' \
> --output /etc/mrtg/mrtg.cfg \
> --ifref=ip \
> 205.71.38.xxx

indexmaker --output /home/WWW/www/mrtg/index.html /etc/mrtg/mrtg.cfg

 mrtg /etc/mrtg/mrtg.cfg

mrtg /etc/mrtg/mrtg.cfg

mrtg /etc/mrtg/mrtg.cfg

然後就可以去看是否產生流量統計圖表了
