Because I couldn’t find any that worked.

I talked about MRTG stats for Squid in the past but apparently forgot to include the .mib file.

So, here it is. Download this file and put it in /usr/share/squid/mib.txt.

I don’t quite remember where I found that mib file. Probably included with Squid on Gentoo or the world wide web… But I couldn’t find it on Debian, so here it is. And be sure to add these lines to your Squid config:

I tend to restart OpenVPN a lot due to config changes. As a result, this brings quite some issues to MRTG (or more precisely, SNMP), due to the fact tun devices change of ID.

A while back, I found a quick fix for this; rename the interface targets from their respective ID to their name:

Target[eth0]: 2:public@localhost

becomes

Target[eth0]: #eth0:public@localhost

#
# Eth0 stats
#
Options[eth0]: growright, nobanner, pngdate, nopercent, noinfo
Target[eth0]: #eth0:public@localhost:
SetEnv[eth0]: MRTG_INT_DESCR="eth0"
MaxBytes[eth0]: 1250000
Title[eth0]: Traffic Analysis for deng
PageTop[eth0]: <H1>Traffic Analysis for deng (eth0)</H1>
#
# Eth1 stats
#
Options[eth1]: growright, nobanner, pngdate, nopercent, noinfo
Target[eth1]: #eth1:public@localhost:
SetEnv[eth1]: MRTG_INT_DESCR="eth1"
MaxBytes[eth1]: 1250000
Title[eth1]: Traffic Analysis for deng
PageTop[eth1]: <H1>Traffic Analysis for deng (eth1)</H1>
#
# tun0 stats

Options[tun0]: growright, nobanner, pngdate, nopercent, noinfo

Only because stats are pretty awesome. The effects of my media attention a few days ago. I’ll give some more info than what can be seen here.

And pretty happy I set up my nginx caching up a few weeks ago.

MRTG traffic stats on vm1, my nginx caching server, of the first 2 days (only major traffic source is this blog):

Top referrers (though not 100% accurate):

As I often have people asking for the files I use to make my pretty MRTG graphs; I’ll publish them here.

Here are some examples:

Zero - One - Four - vm1 - Sauron

The config files:

Sauron (including Squid stats),

Zero (including fan stats).

List of files included:

• indexmaker; simple script (included with MRTG) to generate a simple index file with all the graphs
• snmp-if.sh; will show you the IDs of the interfaces on the server/pc. These IDs have to be edited in the mrtg.cfg file; e.g.:

Target[eth0]: 2:public@localhost:
