Thanks for sharing. If anyone can test and provide a feedback, it's welcome.

#!/usr/bin/perl

use strict;
use warnings;

use RRD::Simple();

my $rrd_file = "./orig.rrd";
my $rrd = RRD::Simple->new();

print "Processing $rrd_file...";
$rrd->add_source($rrd_file, 'APACHE2' => 'GAUGE');
print " ok.\n";

You're right!

Thanks for highlighting that.

It should have been done by something like that first:

rrdtool create eau2.rrd --start 1202484376 \

DS:HWH:GAUGE:288:U:U \

DS:HWL:GAUGE:288:U:U \

DS:ROOM:GAUGE:288:U:U \

RRA:AVERAGE:0.5:1:12 \

RRA:AVERAGE:0.5:1:288 \

RRA:AVERAGE:0.5:1:2016 \

RRA:AVERAGE:0.5:1:8928 \

RRA:AVERAGE:0.5:1:105408 \

RRA:AVERAGE:0.5:1:316224

to create the eau2.rd, then editing the file by adding <ds> tag. Your dump file should already contain something like:

        <ds>

                <name> HWH </name>

                <type> GAUGE </type>

                <minimal_heartbeat> 288 </minimal_heartbeat>

                <min> NaN </min>

                <max> NaN </max>



                <!-- PDP Status -->

                <last_ds> 55 </last_ds>

                <value> 1.0130448955e+04 </value>

                <unknown_sec> 0 </unknown_sec>

        </ds>

so you should add that 2 times with the new fields name.

        <ds>

                <name> HWL </name>

                <type> GAUGE </type>

                <minimal_heartbeat> 288 </minimal_heartbeat>

                <min> NaN </min>

                <max> NaN </max>



                <!-- PDP Status -->

                <last_ds> 53.5 </last_ds>

                <value> 9.8541639835e+03 </value>

                <unknown_sec> 0 </unknown_sec>

        </ds>



        <ds>

                <name> ROOM </name>

                <type> GAUGE </type>

                <minimal_heartbeat> 288 </minimal_heartbeat>

                <min> NaN </min>

                <max> NaN </max>



                <!-- PDP Status -->

                <last_ds> -19.5 </last_ds>

                <value> -3.5917046295e+03 </value>

                <unknown_sec> 0 </unknown_sec>

        </ds>

It works, but I think you have forgotten to define the new column beforse the rra tag
