MRTG configuration

[Draemad]

Does anybody have a good guide to setting up mrtg?

I am trying to set it up to monitor my dlink dsl 504 modem/router. dlink claims it supports snmp, so I am assuming I can configure mrtg to do this.

Is it possible?

mrtg.planetmirror.com and http://people.ee.ethz.ch/~oetiker/webtools/mrtg/ would be good places to start. Plenty of mirrors and docs around to use.

I started to try and change a few settings on IPCop (yes I'm possibly changing firewall camps) to do with MRTG graphing but there are not a lot of options with the graphs themselves. The preferred option seems to be to use RRDtool with MRTG.

I'm looking at -->trying<-- my hand at putting ipac-ng graphs on IPCop 1.3.0 (which I believe is what is going on the next version of IPCop?).

Sorry, no tips to help you directly, but hopefully some links that might be useful?

There are plenty of HOW-TO files out there for actually installing MRTG on your system. I'll assume that you can at least get it installed. The big challenge is normally writing the config file, so to help you there...

Here is my ADSL.cfg file.

This assumes your router LAN IP is 10.0.0.138, that you have downloaded the dsl500.mib from D-link and you're using the default E-Smith directory structure. Obviously you'll need to update this to suit your installation.

Notes:
Progressive totals reset back to 0 at approximately 4GB.
Current totals show traffic passed in the last 5 minutes.
Capacity Available doesn't seem to change much - I think it's a feature not implemented in Australia.
Some of the titles, headings, etc could probably do with some cleanup.

There are also several error counting registers that you can find if you snp-walk the device. Due to an NDA, I can't give you the details of those here.

I have tried to find the dsl504.mib file but have had no luck?

Do you have a link.

Also when attempting to use the cfgmaker I get the following error:

C:\MRTG\bin>perl cfgmaker --noreversedns private@192.168.0.1 --output adsl.cfg
--base: Get Device Info on private@192.168.0.1:

Any idea's?

[Draemad]

woot!

Figured out what was wrong!

That teach me to block perl from accessing my router by zonealarm...

email D-Link for the 504 MIB file. I can't link the one I have as it's a reseller/ISP-only version (has certain restricted entries, etc).
