I find pnp4nagios is the easiest way to generate bandwidth graphs as well as other grpahs in nagios

1. You need to install and configure MRTG first.
Please check this guide for the setup and configuration
http://oss.oetiker.ch/mrtg/doc/mrtg-unix-guide.en.html
2. The integrate Nagios with MRTG
You can use Nagiostats utility, which comes with Nagios standard installation.
Here is the guide (check the "MRTG integration" section)
http://nagios.manubulon.com/traduction/docs25en/nagiostats.html
Or use some other tool like serverscheck (You need to configure your network device to send out SNMP trap)

thx wesly for guiding me through steps. i am trying to configure mrtg from the given link

when i am running mrtg by this command /usr/local/mrtg-2/bin/mrtg
[root@xav-ind-lap-48 ~]# /usr/local/mrtg-2/bin/mrtg
--------------------------
ERROR: Mrtg will most likely not work properly when the environment
variable LANG is set to UTF-8. Please run mrtg in an environment
where this is not the case. Try the following command to start:
