Defined Type: logstash::input::log4j

Defined in:
manifests/input/log4j.pp

Overview

Define: logstash::input::log4j

Read events over a TCP socket from Log4j SocketAppender.  Can either
accept connections from clients or connect to a server, depending on
mode. Depending on mode, you need a matching SocketAppender or
SocketHubAppender on the remote side

Parameters

add_field

Add a field to an event Value type is hash Default value: {} This variable is optional

charset

The character encoding used in this input. Examples include “UTF-8” and “cp1252” This setting is useful if your log files are in Latin-1 (aka cp1252) or in another character set other than UTF-8. This only affects “plain” format logs since json is UTF-8 already. Value can be any of: “ASCII-8BIT”, “UTF-8”, “US-ASCII”, “Big5”, “Big5-HKSCS”, “Big5-UAO”, “CP949”, “Emacs-Mule”, “EUC-JP”, “EUC-KR”, “EUC-TW”, “GB18030”, “GBK”, “ISO-8859-1”, “ISO-8859-2”, “ISO-8859-3”, “ISO-8859-4”, “ISO-8859-5”, “ISO-8859-6”, “ISO-8859-7”, “ISO-8859-8”, “ISO-8859-9”, “ISO-8859-10”, “ISO-8859-11”, “ISO-8859-13”, “ISO-8859-14”, “ISO-8859-15”, “ISO-8859-16”, “KOI8-R”, “KOI8-U”, “Shift_JIS”, “UTF-16BE”, “UTF-16LE”, “UTF-32BE”, “UTF-32LE”, “Windows-1251”, “BINARY”, “IBM437”, “CP437”, “IBM737”, “CP737”, “IBM775”, “CP775”, “CP850”, “IBM850”, “IBM852”, “CP852”, “IBM855”, “CP855”, “IBM857”, “CP857”, “IBM860”, “CP860”, “IBM861”, “CP861”, “IBM862”, “CP862”, “IBM863”, “CP863”, “IBM864”, “CP864”, “IBM865”, “CP865”, “IBM866”, “CP866”, “IBM869”, “CP869”, “Windows-1258”, “CP1258”, “GB1988”, “macCentEuro”, “macCroatian”, “macCyrillic”, “macGreek”, “macIceland”, “macRoman”, “macRomania”, “macThai”, “macTurkish”, “macUkraine”, “CP950”, “Big5-HKSCS:2008”, “CP951”, “stateless-ISO-2022-JP”, “eucJP”, “eucJP-ms”, “euc-jp-ms”, “CP51932”, “eucKR”, “eucTW”, “GB2312”, “EUC-CN”, “eucCN”, “GB12345”, “CP936”, “ISO-2022-JP”, “ISO2022-JP”, “ISO-2022-JP-2”, “ISO2022-JP2”, “CP50220”, “CP50221”, “ISO8859-1”, “Windows-1252”, “CP1252”, “ISO8859-2”, “Windows-1250”, “CP1250”, “ISO8859-3”, “ISO8859-4”, “ISO8859-5”, “ISO8859-6”, “Windows-1256”, “CP1256”, “ISO8859-7”, “Windows-1253”, “CP1253”, “ISO8859-8”, “Windows-1255”, “CP1255”, “ISO8859-9”, “Windows-1254”, “CP1254”, “ISO8859-10”, “ISO8859-11”, “TIS-620”, “Windows-874”, “CP874”, “ISO8859-13”, “Windows-1257”, “CP1257”, “ISO8859-14”, “ISO8859-15”, “ISO8859-16”, “CP878”, “Windows-31J”, “CP932”, “csWindows31J”, “SJIS”, “PCK”, “MacJapanese”, “MacJapan”, “ASCII”, “ANSI_X3.4-1968”, “646”, “UTF-7”, “CP65000”, “CP65001”, “UTF8-MAC”, “UTF-8-MAC”, “UTF-8-HFS”, “UTF-16”, “UTF-32”, “UCS-2BE”, “UCS-4BE”, “UCS-4LE”, “CP1251”, “UTF8-DoCoMo”, “SJIS-DoCoMo”, “UTF8-KDDI”, “SJIS-KDDI”, “ISO-2022-JP-KDDI”, “stateless-ISO-2022-JP-KDDI”, “UTF8-SoftBank”, “SJIS-SoftBank”, “locale”, “external”, “filesystem”, “internal” Default value: “UTF-8” This variable is optional

data_timeout

Read timeout in seconds. If a particular tcp connection is idle for more than this timeout period, we will assume it is dead and close it. If you never want to timeout, use -1. Value type is number Default value: 5 This variable is optional

debug

Set this to true to enable debugging on an input. Value type is boolean Default value: false This variable is optional

format

The format of input data (plain, json, json_event) Value can be any of: “plain”, “json”, “json_event”, “msgpack_event” Default value: None This variable is optional

host

When mode is server, the address to listen on. When mode is client, the address to connect to. Value type is string Default value: “0.0.0.0” This variable is optional

message_format

If format is “json”, an event sprintf string to build what the display @message should be given (defaults to the raw JSON). sprintf format strings look like %fieldname or %@metadata. If format is “json_event”, ALL fields except for @type are expected to be present. Not receiving all fields will cause unexpected results. Value type is string Default value: None This variable is optional

mode

Mode to operate in. server listens for client connections, client connects to a server. Value can be any of: “server”, “client” Default value: “server” This variable is optional

port

When mode is server, the port to listen on. When mode is client, the port to connect to. Value type is number Default value: None This variable is required

tags

Add any number of arbitrary tags to your event. This can help with processing later. Value type is array Default value: None This variable is optional

type

Label this input with a type. Types are used mainly for filter activation. If you create an input with type “foobar”, then only filters which also have type “foobar” will act on them. The type is also stored as part of the event itself, so you can also use the type to search for in the web interface. If you try to set a type on an event that already has one (for example when you send an event from a shipper to an indexer) then a new input will not override the existing type. A type set at the shipper stays with that event for its life even when sent to another LogStash server. Value type is string Default value: None This variable is required

instances

Array of instance names to which this define is. Value type is array Default value: [ ‘array’ ] This variable is optional

Extra information

This define is created based on LogStash version 1.1.12
