[mrtg] Monitoring cable modem connection

[Jake Colman]

First, the good news.  I do have snmpd and mrtg running and creating graphs
for me.  

Now the bad news.  I have no idea what I am graphing!

By doing a bunch of research at various sites, I created the following
snmpd.conf file:

===================================================

com2sec local localhost public
group MyROGroup v1  local
group MyROGroup v2c local
group MyROGroup usm local
view all included  .1                               80
access MyROGroup ""      any       noauth    exact  all    none   none

===================================================

Quite frankly, I have no idea exactly what this does but it seems
sufficient.   An explanation of what this means would be nice.

I have the following in my mrtg.cfg file:

===================================================

Target[r1]: 2:public at localhost
MaxBytes[r1]: 1250000
Title[r1]: Traffic Analysis
PageTop[r1]: <H1>Ethernet Statistics</H1>

===================================================

It is not clear to me whether port 2 corresponds to eth0 or eth1 or to
something else entirely.  What is it and how do you know?  In other words,
where should I have looked to find the answer?

Next, my intention here is to monitor the throughput I am getting from my
cable provider. My cable modem is connected to eth0.  My internal network is
connected to eth1.  What should I be monitoring to get the results I'd like
to see?

Thanks!

...Jake
