I’m monitoring with MRTG some RouterOS variables in order to get
a idea how it is working.
This is my script to monitor CACHE HITS on my ROUTER OS 3.0rc11
#!/usr/bin/perl
$SSH=“/usr/bin/ssh”;
$USERMT=“linux”;
$CERTMT=“/root/.ssh/id_dsa”;
$HOSTMT=“168.192.1.2”;###################################################################
sub script {
my $linea = shift;
$script.=$linea." \n";
}
###################################################################
sub run {
my $ejecutar = shift;
my $resultado =$ejecutar;
}
###################################################################
sub ejecutarScript {
my($CMD) = shift;
run(“$SSH -l $USERMT -i $CERTMT $HOSTMT "$CMD"”);
}###################################################################
M A I N
###################################################################
#################### Inicializacion Script
script(“#”);
script(“# Inicializacion del script en $theTime “);
script(”#”);script(“/ip proxy monitor once”);
$resultado=ejecutarScript($script);$resultado=~/requests:\s+(\d+)/gi;
$requests=$1;
$resultado=~/hits:\s+(\d+)/gi;
$hits=$1;
print “$requests\n$hits\n”;
And this is my MRTG code:
############### HITS CACHE #################

You need to create ssh certificates in order to run securely your
script.
