> /etc/mrtg/mrtg.cfg

2.       customize /etc/mrtg/mrtg.cfg

sed –i ‘s/localhost_th0/eth0/g’ /etc/mrtg/mrtg.cfg

3.       run mrtg three times to build and populate required files

see /etc/cron.d/mrtg for default syntax and frequency

must be done after any change to /etc/mrtg/mrtg.cfg

 

Allowing access to MRTG

Iostat , sar, awk yum –y install sysstat

 

掌握知识点：SNMP,MRTG,Gnuplot,Syslog,awk,

 

 

 

自己做实验：

虚拟机配置三台：

一台主监控机 redhat 5.4 192.168.0.1

被监控机器 redhat 5.4 192.168.0.3

被监控机器windows server 2003 192.168.0.5

目的：使用snmp协议版本1配合图形化监控工具MRTG监控windows和linux端口流量
