Worked out of the box and did exactly what I needed. I just did a quick Spanish to English translation on some of the outputs and was good to go.

Hi,
this bug https://bugzilla.redhat.com/show_bug.cgi?id=552522 force me to graph not only the usage but also the MAX.
this is the diff with the original
diff check_conn2 check_conntrack.sh
42c42
echo "OK - $COUNT |con=$COUNT"
48c48
echo "WARNING - $COUNT |con=$COUNT"
53c53
echo "CRITICAL - $COUNT |con=$COUNT"
and this is the template for nagios
cat /usr/share/nagios/html/pnp4nagios/templates/check_conntrack.php
DS;
$opt[$i] = "--vertical-label \"ip-conntrack \" -l 0 -r --title \"ip-conntrack metrics for $hostname / $servicedesc\" ";
$def[$i] = '';
$color1 = '#028482';
$color3 = '#B5FF6C';
$def[$i] .= rrd::def ("ipconn-now", $DS[0]['RRDFILE'], $DS[0]['DS'], "AVERAGE") ;
$def[$i] .= rrd::def ("ipconn-max", $DS[1]['RRDFILE'], $DS[1]['DS'], "AVERAGE") ;
$def[$i] .= rrd::area ("ipconn-max", $color3, 'Total' );
$def[$i] .= rrd::gprint ("ipconn-max", array("LAST","MAX","AVERAGE"), "%4.3lf %S".$DS[0]['UNIT']);
$def[$i] .= rrd::line1 ("ipconn-now", $color1, "LastMin " );
$def[$i] .= rrd::gprint ("ipconn-now", array("LAST","MAX","AVERAGE"), "%4.3lf %S".$DS[1]['UNIT']);
?>
