The following documentation is automatically generated.  Please do not edit
this file, but rather the original, inline with Net::Async::OpenTracing
at lib/Net/Async/OpenTracing.pm
(on the system that originally ran this).
If you do edit this file, and don't want your changes to be removed, make
sure you change the first line.


=head1 NAME

Net::Async::OpenTracing - basic proof-of-concept implementation for OpenTracing APM


This all relies on the abstract L<OpenTracing> interface, so that'd be
the first port of call for official documentation.

=head2 Setting up and testing

Start up a Jæger instance in Docker like so:

 docker run -d --name jaeger \
  -p 5775:5775/udp \
  -p 6831:6831/udp \
  -p 6832:6832/udp \
  -p 5778:5778 \
  -p 16686:16686 \
  -p 14268:14268 \
  -p 9411:9411 \

Set up an L<Net::Async::OpenTracing> instance with those connection details:

 my $loop = IO::Async::Loop->new;
    my $tracing = Net::Async::OpenTracing->new(
        host => '',
        port => 6832,
  my $batch = $tracing->new_batch();
  my $span = $batch->new_span(
  $span->log('test message ' . $_ . ' from the parent') for 1..3;
  my $child = $span->new_span('child_span');
  $child->log('message ' . $_ . ' from the child span') for 1..3;
 # Make sure all trace data is sent

You should then see a trace with 2 spans show up.
