Yes it is MRTG.

  1. In the station I want to monitor, I run the wlan.pl script I found from http://www.linux-magazin.de/ausgabe/2000/08/Wavelan/WaveLAN.html
  2. Then in that machine where the MRTG is running you can run script something like this.

#!/usr/bin/perl
#

my($machine);
#

$ssh = "/usr/bin/ssh -x";
#

if (scalar(@ARGV) < 1)

   {
   print("USAGE: linkquality.pl {machine}\n");    exit(-1);
   }
#

if ($ARGV[0] ne '' && $ARGV[0] ne '#')

   {
   $machine = $ARGV[0];
   }
#

$getquality = `$ssh $machine "/usr/local/bin/wlan.pl"`;
#

exit(0);

3. To mrtg.cfg you can put something like this.
