Did some more debugging: The section below seems to be having a bit of a
problem:

            # If the RRD not exists:
            if ( !( -e $file ) ) {

                # Adding Graph Value Key's
                foreach (@blocks) {
                    if ( $service =~ /$_->{service_name}/ ) {

                        # change the default rrdtype if a different is defined
                        my $rrd_type = "GAUGE";
                        $rrd_type = $_->{rrd_type} if ( exists( $_->{rrd_type} ) );

                         # setting the heartbeat#
                        if (!defined($heartbeat)) {
                                $heartbeat = $default_heartbeat;
                                $heartbeat = $_->{heartbeat} if ( exists( $_->{heartbeat} ));
                        }

                        # setting the step
                        if (!defined($step)) {
                            $step = $default_step;
                            $step = $_->{step} if ( exists( $_->{step} ));
                        }

                        push @system,
                          "DS:"
                          . $_->{graph_value} . ":"
                          . $rrd_type
                          . ":". $heartbeat. ":U:U";
                    }
                }

                # Adding some default average frames
                push @system, "RRA:AVERAGE:0.5:5:$heartbeat";
                push @system, "RRA:MAX:0.5:5:$heartbeat";
                push @system, "RRA:MIN:0.5:5:$heartbeat";
                push @system, "RRA:AVERAGE:0.5:30:$heartbeat";
                push @system, "RRA:MAX:0.5:30:$heartbeat";
                push @system, "RRA:MIN:0.5:30:$heartbeat";
                push @system, "RRA:AVERAGE:0.5:120:$heartbeat";
                push @system, "RRA:MAX:0.5:120:$heartbeat";
                push @system, "RRA:MIN:0.5:120:$heartbeat";
                push @system, "RRA:AVERAGE:0.5:1440:$heartbeat";
                push @system, "RRA:MAX:0.5:1440:$heartbeat";
                push @system, "RRA:MIN:0.5:1440:$heartbeat";

Which I noticed with the following (DEBUG) line added for debugging
purposes:

                if($opt_verbose & $LOG_RRD_STATUS) {
                        $dummy="";
                        foreach (@system) {
                                $dummy.=$_. ' ';
                        }
                        print_log("DEBUG: step=$step defaultstep=$default_step heartbeat=$heartbeat defaultheartbeat=$default_heartbeat");
                        print_log("RRD: rrdtool create $file --step=$step $dummy");
                }

Both $step and $heartbeat were empty for these cases. And the log is
missing the DS sections all together. I seem to have the fixed the $step
issue a bit the missing DS is a real killer.

I need to do even more debugging here.

Hugo.
