push custom software XML from agent plugin

Question

Hello,

Trying to move from fusioninventory (FI) to OCS. I used FI to add custom softwares to the agent report. Trying to do the same with OCS.

So I wrote a plugin, starting from the Example.pm plugin. Here's the inventory_handler function :

sub freepbx_inventory_handler {        #Use this hook to add or modify entries in the inventory XML
    my $self = shift;
    my $logger = $self->{logger};

    $logger->debug("Yeah you are in freepbx_inventory_handler :)");
    my $json = JSON->new->utf8->boolean_values(0, 1);  # false → 0, true → 1
    # JSON string
    my $json_text = `/usr/sbin/fwconsole ma list --format json | tail -n1`;

    # Decode JSON to perl object
    my $decoded = $json->decode($json_text);

    my @modules;
    foreach my $entry (@{$decoded->{data}}) {
        push @modules, {
            NAME     => $entry->[0],
            VERSION  => $entry->[1],
            PUBLISHER => $entry->[4],
            FROM => 'freepbx'
        };
    }

    my $data_for_xml = {
        SOFTWARES => \@modules
    };

    # Convert to XML
    my $xml = XMLout($data_for_xml, XMLDecl => 0, NoAttr => 1, RootName => undef);
    my $xml = XMLout($data);
    $logger->debug($xml);
    push @{ $inventory->{xmlroot}->{'CONTENT'} },{ $xml };
}

When running this part of script standalone, it returns stuff like :

  <SOFTWARES>
    <FROM>freepbx</FROM>
    <NAME>userman</NAME>
    <PUBLISHER>Sangoma</PUBLISHER>
    <VERSION>16.0.44</VERSION>
  </SOFTWARES>
  <SOFTWARES>
    <FROM>freepbx</FROM>
    <NAME>voicemail</NAME>
    <PUBLISHER>Sangoma</PUBLISHER>
    <VERSION>16.0.49</VERSION>
  </SOFTWARES>
  <SOFTWARES>
    <FROM>freepbx</FROM>
    <NAME>webrtc</NAME>
    <PUBLISHER>Sangoma</PUBLISHER>
    <VERSION>16.0.17</VERSION>
  </SOFTWARES>

But when running ocsinventory-agent -l=./, I don't see this output in the generated .ocs file

What am I doing wrong ? Is there some doc somewhere ?

Regards
