Now, below is MRTG-config reading the cyberdo-node at port 15717, syberdo_slave4 at port 15720, and one reading from the machine itself. My readings can be seen at: http://www.acc.umu.se/~cyberdo/snmp/mrtg/_index.htm∞

Additions:
.1.3.1.1.m.n Amount of incoming/outgoing data during the last (m*30)s-period before the current 30s-period
for instance: .1.3.1.1.9.1 is the amount of incoming data the prev. 5 min.
Now, here's my MRTG-config reading the cyberdo-node at port 15717, syberdo_slave4 at port 15720, and one reading from the machine itself:
To make it work, I use a little script placed at /etc/mrtg/tools/memused.sh (change the references below if you change the location):

#!/bin/sh
if [ "$1" == "" ] ; then
	    echo "$0 <hostname[:port]> <community>" ;exit 1
fi
totalmem=`snmpget -v 1 -O vq -c "$2" "$1" memTotalReal.0`
freemem=`snmpget -v 1 -O vq -c "$2" "$1" memAvailReal.0`
expr $totalmem - $freemem
echo $totalmem
And finally, the snmp-conf:

["This is just a stub"]

From version 420 fred has a SNMP-Sgent (server) built in.
It operates at UDP port (freenetport + 4000).

The below OID:s are extremely temporary and might very well change.

.1.3.1.1.x.0 is for outgoing data (notice that the 1 looks like an I)
.1.3.1.1.x.1 is for incoming data (notice that the 1 looks like an I)

.1.3.1.1.0.n Total amount of incoming/outgoing data during the current run

.1.3.1.1.1.n Amount of incoming/outgoing data during the last 30s-period before the current 30s-period
.1.3.1.1.2.n Amount of incoming/outgoing data during the last 60s-period before the current 30s-period
.1.3.1.1.3.n Amount of incoming/outgoing data during the last 90s-period before the current 30s-period
.1.3.1.1.4.n Amount of incoming/outgoing data during the last 120s-period before the current 30s-period
.1.3.1.1.5.n Amount of incoming/outgoing data during the last 180s-period before the current 30s-period
.1.3.1.1.6.n Amount of incoming/outgoing data during the last 210s-period before the current 30s-period
.1.3.1.1.7.n Amount of incoming/outgoing data during the last 240s-period before the current 30s-period
.1.3.1.1.8.n Amount of incoming/outgoing data during the last 270s-period before the current 30s-period
.1.3.1.1.9.n Amount of incoming/outgoing data during the last 300s-period before the current 30s-period
