There is a tool to make this.......mrtg
cfgmaker
I used this command and then edited the mrtg.cfg
file to my HTML tastes......
/usr/bin/cfgmaker --global 'WorkDir:
/var/www/html/mrtg' --global 'Options[_]: bits,growright' --output
/etc/mrtg/mrtg.cfg MYCOMMSTRING@192.168.1.50
My SNMP config file: ((Edited for my comm strings
-- mycommstring is substituted))
<snip>

com2sec mynetwork 192.168.1.0/24 MYCOMMSTRING2

I do not allow my router to pass SNMP traffic out
my WAN interface, but I still setup the SNMP comm strings as non public and
private.....safer...paranoid??? Don't care...safer...
