=head1 NAME

AnyEvent::Porttracker - Porttracker/PortIQ API client interface.

=head1 SYNOPSIS

   use AnyEvent::Porttracker;

   my $api = new AnyEvent::Porttracker
      host => "10.0.0.1",
      user => "admin",
      pass => "31331",
      tls  => 1,
   ;

   # Example 1
   # a simple request: ping the server synchronously

   my ($timestamp, $pid) = $api->req_sync ("ping");

   # Example 2
   # find all realms, start a discovery on all of them
   # and wait until all discovery processes have finished
   # but execute individual discoveries in parallel,
   # asynchronously

   my $cv = AE::cv;

   $cv->begin;
   # find all realms
   $api->req (realm_info => ["gid", "name"], sub {
      my ($api, @realms) = @_;

      # start discovery on all realms
      for my $realm (@realms) {
         my ($gid, $name) = @$realm;

         $cv->begin;
         $api->req (realm_discover => $gid, sub {
            warn "discovery for realm '$name' finished\n";
            $cv->end;
         });
      }

      $cv->end;
   });

   $cv->recv;

   # Example 3
   # subscribe to realm_poll_stop events and report each occurance

   $api->req (subscribe => "realm_poll_stop", sub {});
   $api->on (realm_poll_stop_event => sub {
      my ($api, $gid) = @_;
      warn "this just in: poll for realm <$gid> finished.\n";
   });

   AE::cv->recv; # wait forever

=head1 DESCRIPTION

Porttracker (L<http://www.porttracker.com/>) is a product that (among
other things) scans switches and routers in a network and gives a coherent
view of which end devices are connected to which switch ports on which
switches and routers. It also offers a JSON-based client API, for which
this module is an implementation.

In addition to Porttracker, the PortIQ product is also supported, as it
uses the same protocol.

If you do not have access to either a Porttracker or PortIQ box then this
module will be of little value to you.

This module is an L<AnyEvent> user, you need to make sure that you use and
run a supported event loop.

To quickly understand how this module works you should read how to
construct a new connection object and then read about the event/callback
system.

The actual low-level protocol and, more importantly, the existing
requests and responses, are documented in the official Porttracker
API documentation (a copy of which is included in this module as
L<AnyEvent::Porttracker::protocol>.
