Tool for recording wireless values

[ASID]

Does anyone know any tool that is able to record values from the wireless interface?
For example, I want to record the signal level (dbm) of my card for one day. This information is available with the iwconfig, but I cannot store these values.
Is there a tool available to keep this kind of statistics?

I don't know any application to do this...
Well, if you just want to record one value, you can just write a shell script for this...
for example

while (true); do
echo -n `date +"%F %T"` >> $LOGFILE
echo -n ";" >> $LOGFILE
sudo iwconfig $IFACE 2>/dev/null | sed -n -e '/Signal/p >> $LOGFILE
echo "" >> $LOGFILE
done

this generates a CSV file containing date/time plus the relevant line of iwconfig output...
then you can open this in OOo's Calc or whatever you like and make nice plots :-)
or else use gnuplot to generate them on the fly!

Thanx a lot mottmar!!
I looked around and found a tool called "collectd" which collects various statistics. I tried it but it couldn't record some values that I wanted it to.

So I followed your approach and created a script which does exactly what I want.

Cheers!

I'm happy my suggestion was useful for you!
