UDP and UNIX Socket Input

1. Sample Configuration

filename            = "udp.lua"
instruction_limit   = 0

-- address (string) - An IP address (* for all interfaces), or a path to a UNIX
-- socket.
-- Default:
-- address = "127.0.0.1"

-- port (integer) - IP port to listen on (ignored for UNIX socket).
-- Default:
-- port = 514

-- default_headers (table) - Sets the message headers to these values if they
-- are not set by the decoder.
-- This input will always default the Fields.sender_ip and Fields.sender_port
-- for non UNIX sockets.
-- Default:
-- default_headers = nil

-- printf_messages = -- see: https://mozilla-services.github.io/lua_sandbox_extensions/lpeg/modules/lpeg/printf.html

-- Specifies a module that will decode the raw data and inject the resulting message.
-- Supports the same syntax as an individual sub decoder
-- see: https://mozilla-services.github.io/lua_sandbox_extensions/lpeg/io_modules/lpeg/sub_decoder_util.html
-- Default:
-- decoder_module = "decoders.heka.protobuf"

-- send_decode_failures (bool) - When true a decode failure will inject a
-- message with the following structure:
-- msg.Type = "error.<category>"
-- msg.Payload = "<error message>"
-- msg.Fields.data = "<data that failed decode>"
-- Default
-- send_decode_failures = false
