NAME ^

Log::UDP::Client - A simple way to send structured log messages via UDP

VERSION ^

version 0.20.2

SYNOPSIS ^

    use Log::UDP::Client;

    # Send the simple scalar to the server
    Log::UDP::Client->new->send("Hi");

    # Log lots of messages
    my $logger = Log::UDP::Client->new(server_port => 15000);
    my $counter=0;
    while(++$counter) {
        $logger->send($counter);
        last if $counter >= 1000;
    }

    # Send some debugging info
    $logger->send({
        pid     => $$,
        program => $0,
        args    => \@ARGV,
    });

    # Use of JSON serializer
    my $logger = Log::UDP::Client->new( serializer_module => 'JSON' );

    # Will emit { "message" => "Hi" } because JSON want to wrap stuff into a hashref
    $logger->send("Hi");

    # Use of custom serializer
    use Storable qw(freeze);
    my $logger = Log::UDP::Client->new (
        serializer => sub {
            return nfreeze( \( $_[0] ) );
        },
    );

DESCRIPTION ^

This module enables you to send a message (simple string or complicated object) over an UDP socket to a listening server. The message will be encoded with a serializer module (default is Storable).

ATTRIBUTES ^

server_address : Str

IP address or hostname for the server you want to send the messages to. This field can be changed after instantiation. Default is 127.0.0.1.

server_port : Int

Port for the server you plan to send the messages to. This field can be changed after instantiation. Default is port 9999.

throws_exception : Bool

If errors are encountered, should we throw exception or just return? Default is return. Set to true for exceptions. You can change this flag after instantiation.

socket : IO::Socket::INET

Read-only field that contains the socket used to send the messages.

METHODS ^

send($message)

Instance method that actually encodes and transmits the specified message over UDP to the listening server. Will die if throw_exception is set to true and some kind of transmission error occurs. The message will be serialized by the instance-defined serializer. Returns true on success.

INHERITED METHODS ^

All of these methods are inherited from Data::Serializable. Read more about them there.
