Monitor your adsl bandwith usage

I use fedora 6, mrtg and snmp tools to monitor adsl router bandwith for all interfaces (wlan,atm,lan)

install packages:
net-snmp
net-snmp-utils
mrtg
You can install yum install packagename. Or download package and rpm -ivh package name.

configure mrtg:
for snmp v1:
cfgmaker --output=/etc/mrtg/mrtg.cfg --global \
"workdir: /var/www/mrtg" -ifref=ip \
--global 'options[_]: growright,bits' public@192.168.2.1
for snmp v2:

cfgmaker --output=/etc/mrtg/192.168.2.1.cfg \
-ifref=ip --global "workdir: /var/www/mrtg" \
--snmp-options=:::::2 public@192.168.2.1



for public@192.168.2.1 use your snmp community and your adsl router ip address.
check your /etc/mrtg/mrtg.cfg and comment out interfaces you want to monitor.

run this command three times to collect data. You will get error for the first two times.
env LANG=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg

make your html page:
indexmaker --output=/var/www/mrtg/index.html \
/etc/mrtg/mrtg.cfg

put configuration to crontab:
0-59/5 * * * * root env LANG=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg

httpd configuration:
edit configuration /etc/httpd/conf.d/mrtg.conf and comment deny restrictions if you want to access your http service remotely.
then start service
service httpd start

enable this service
chkconfig httpd on
