It seems that everything is in order ... But.
Sometimes I get the right graph .. And the sometimes I get an all different
graph ?!!?

I've attached the 2 different graphs.

This is the way I do it :

Crontab:
*/4 * * * * /usr/local/rrdtool-1.0.33/bin/start_rrdtool

Start_rrdtool:
Cd /usr/local/rrdtool-1.0.33/bin
./router


Router script:

#!/usr/bin/perl

# RRD script

use lib qw( /usr/local/rrdtool-1.0.33/lib/perl ../lib/perl );
use RRDs;



# Get the InOctets of the router and get the value of the complete string


@in =`snmpget <ip> public 2.2.1.10.4`; 
for (@in){
	@regel=split;
	$in=$regel[3];
    	}

	
# Get the OutOctets of the router and get the value of the complete string

@out =`snmpget <ip> public 2.2.1.16.4`;
for (@out){
	@regel=split;
	$out=$regel[3];
	}



# Make the update of router.rrd

 RRDs::update ("/usr/local/rrdtool-1.0.33/bin/router.rrd","N:$in:$out");
 my $ERR=RRDs::error;
 die "ERROR while updating router.rrd: $ERR\n" if $ERR;


RRDs::graph "/usr/local/rrdtool-1.0.33/bin/router-day.gif",
        "--start", " -86400",
        "--title", "Ethernet0 stats per day",
        "--rigid",
        "--width=600",
        "--height=250",
        "--upper-limit","10000",
        "--lower-limit","0",
        "--vertical-label","bytes/sec",
        "DEF:inoctets=router.rrd:input:AVERAGE",
        "DEF:outoctets=router.rrd:output:AVERAGE",
        "DEF:inoctets2=router.rrd:input:MAX",
        "DEF:outoctets2=router.rrd:output:MAX",
        "AREA:inoctets#FFD700:    In Traffic",
        "GPRINT:inoctets:LAST:Current \\: %8.2lf %s",
        "GPRINT:inoctets:AVERAGE:Avg \\: %8.2lf %s",
        "GPRINT:inoctets:MIN:Min \\: %8.2lf %s",
        "GPRINT:inoctets:MAX:Max \\: %8.2lf %s\\n",
        "AREA:outoctets#FF0000:    Out Traffic",
        "GPRINT:outoctets:LAST:Current \\: %8.2lf %s",
        "GPRINT:outoctets:AVERAGE:Avg \\: %8.2lf %s",
        "GPRINT:outoctets:MIN:Min \\: %8.2lf %s",
        "GPRINT:outoctets:MAX:Max \\: %8.2lf %s\\n",
        "LINE1:inoctets2#00FF00:    Max Input",
        "LINE2:outoctets2#CC00CC:    Max Output";

system("rm /usr/local/rrdtool-1.0.33/html/router-day.gif");
system("cp /usr/local/rrdtool-1.0.33/bin/router-day.gif
/usr/local/rrdtool-1.0.33/html/");

Make sure that you are running rrdtool in the same environment.  This means
that (at least) the current working directory is the same, that the PATH
settings are correct, et cetera.

cheers,
