Has anyone created UUID's in NXLOG? I would like to create an unique
identifier for each event so I can find identical events across hdfs and
elasticsearch.
I tried the following but it only gets me part of the way there:
<Extension perl1>
Module xm_perl
PerlCode /opt/uuid/uuid.pl
</Extension>
<Input in_udp_syslog>
Module im_udp
Host 0.0.0.0
Port 514
Exec perl->call("getuuid");
Exec parse_syslog(); to_json();
</Input>
-------------------------------
/opt/uuid/uuid.pl:
use warnings;
use Data::GUID;
# Without Log::Nxlog you cannot access (read or modify) the event data
# so don't forget this:
use Log::Nxlog;
sub getuuid
{
# The event data is passed here when this method is invoked by the module
my ( $event ) = @_;
my $guid = Data::GUID->new;
Log::Nxlog::set_field_string($event, 'uuid', $guid->as_string);
}
EOF
---------------------------
The above works great until I add it to a second input and nxlog hangs:
<Input in_udp_syslog2>
Module im_udp
Host 0.0.0.0
Port 515
Exec perl->call("getuuid");
Exec parse_syslog(); to_json();
</Input>
I tried adding a second extension pointing at the same perl code and still
no luck
<Extension perl2>
Module xm_perl
PerlCode /opt/uuid/uuid.pl
</Extension>
I am open to other ways to solve the problem of UUIDs but would still like
to know how I could run a common perl script across multiple inputs.
Any help is appreciated!
