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.

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);
}
