[rt-users] How to search update/comment fields and link an asset if its mentioned?

Hey guys,

I'm using Request Tracker 3.8.4 and Asset Tracker 1.2.4 on a Debian Etch
box. RTFM 2.4.2 is also installed. 

When a ticket is created/updated/resolved, I'm trying to search the
contents of the ticket for an asset's hostname. If the hostname is
mentioned in the ticket, then I'd like for a bidirectional link to
automatically be created between the ticket and the asset.

I've downloaded and installed the LinkTicketToAsset scrip, and it works
great for what it was intended for -- whenever I enter an asset's
hostname in the "Asset" custom field, it will create a bidirectional
link between the asset and the ticket. However, I can't figure out how
to modify it to search the entire contents of the ticket, or at least
the comment/reply/resolve sections (the main text sections). 

Here is the custom condition of the LinkTicketToAsset scrip:

my $trans = $self->TransactionObj->Type;
my $new_value = $self->TransactionObj->NewValue;
my $cf_id = $self->TransactionObj->Field;

if ($trans ne 'CustomField') { return 0; }
if (! $new_value) { return 0; }
my $cf = new RT::CustomField($RT::SystemUser);
my ($id,$msg) = $cf->Load($cf_id);

if (!$id) {
   $RT::Logger->crit("Could not load CF: $msg");
   return 0;
if ($cf->Name ne 'Asset') { return 0; }


Here is the cleanup code:

my $new_value = $self->TransactionObj->NewValue;
my $asset = RTx::AssetTracker::Asset->new($self->CurrentUser);
my ($id,$msg) = $asset->Load($new_value);
if (! $id) {
   $RT::Logger->crit("Could not load asset $new_value: $msg");
   return 0;
($id,$msg) = $self->TicketObj->AddLink(Type => 'RefersTo', Target =>
if (! $id) {
   $RT::Logger->crit("Could not AddLink: $msg");
   return 0;

I'm brand new to Asset Tracker scrips so I'm having trouble
understanding what I would need to change to get this scrip to work by
searching the entire ticket instead of just the Asset custom field. I
see where the Asset custom field is mentioned, but I'm not sure what to
replace it with. 

Any help or recommendations on where to begin would be appreciated.
