NAME
       Log::Log4perl::Appender::Socket - Log to a socket

SYNOPSIS
           use Log::Log4perl::Appender::Socket;

           my $appender = Log::Log4perl::Appender::Socket->new(
             PeerAddr => "server.foo.com",
             PeerPort => 1234,
           );

           $appender->log(message => "Log me\n");

DESCRIPTION
       This is a simple appender for writing to a socket. It relies on IO::Socket::INET and
       offers all parameters this module offers.

       Upon destruction of the object, pending messages will be flushed and the socket will be
       closed.

       If the appender cannot contact the server during the initialization phase (while running
       the constructor "new"), it will "die()".

       If the appender fails to log a message because the socket's "send()" method fails (most
       likely because the server went down), it will try to reconnect once. If it succeeds, the
       message will be sent.  If the reconnect fails, a warning is sent to STDERR and the "log()"
       method returns, discarding the message.

       If the option "silent_recovery" is given to the constructor and set to a true value, the
       behaviour is different: If the socket connection can't be established at initialization
       time, a single warning is issued.  Every log attempt will then try to establish the
       connection and discard the message silently if it fails.  If you don't even want the
       warning, set the "no_warning" option to a true value.

       Connecting at initialization time may not be the best option when running under Apache1
       Apache2/prefork, because the parent process creates the socket and the connections are
       shared among the forked children--all the children writing to the same socket could
       intermingle messages.  So instead of that, you can use "defer_connection" which will put
       off making the connection until the first log message is sent.

EXAMPLE
       Write a server quickly using the IO::Socket::INET module:

           use IO::Socket::INET;

           my $sock = IO::Socket::INET->new(
               Listen    => 5,
               LocalAddr => 'localhost',
               LocalPort => 12345,
               Proto     => 'tcp');

           while(my $client = $sock->accept()) {
               print "Client connected\n";
               while(<$client>) {
                   print "$_\n";
               }
           }

       Start it and then run the following script as a client:

           use Log::Log4perl qw(:easy);

           my $conf = q{
               log4perl.category                  = WARN, Socket
               log4perl.appender.Socket           = Log::Log4perl::Appender::Socket
               log4perl.appender.Socket.PeerAddr  = localhost
               log4perl.appender.Socket.PeerPort  = 12345
               log4perl.appender.Socket.layout    = SimpleLayout
           };

           Log::Log4perl->init(\$conf);

           sleep(2);

           for(1..10) {
               ERROR("Quack!");
               sleep(5);
           }
