tcp

Read events over a TCP socket.

Like stdin and file inputs, each event is assumed to be one line of text.

Can either accept connections from clients or connect to a server, depending on mode.

  • There is no default value for this setting.

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.

codec

  • Value type is codec
  • Default value is "line"

The codec used for input data. Input codecs are a convenient method for decoding your data before it enters the input, without needing a separate filter in your Logstash pipeline.

data_timeout

  • Value type is number
  • Default value is -1

The 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.

debug (DEPRECATED)

  • DEPRECATED WARNING: This configuration item is deprecated and may not be available in future versions.
  • Value type is boolean
  • Default value is false

format (DEPRECATED)

  • DEPRECATED WARNING: This configuration item is deprecated and may not be available in future versions.
  • Value can be any of: plain, json, json_event, msgpack_event
  • There is no default value for this setting.

The format of input data (plain, json, json_event)

host

  • Value type is string
  • Default value is "0.0.0.0"

When mode is server, the address to listen on. When mode is client, the address to connect to.

message_format (DEPRECATED)

  • DEPRECATED WARNING: This configuration item is deprecated and may not be available in future versions.
  • Value type is string
  • There is no default value for this setting.

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}

If format is json_event, ALL fields except for @type are expected to be present. Not receiving all fields will cause unexpected results.

mode

  • Value can be any of: server, client
  • Default value is "server"

Mode to operate in. server listens for client connections, client connects to a server.

port

  • This is a required setting.
  • Value type is number
  • There is no default value for this setting.

When mode is server, the port to listen on. When mode is client, the port to connect to.

ssl_cacert

  • Value type is path
  • There is no default value for this setting.

The SSL CA certificate, chainfile or CA path. The system CA path is automatically included.

ssl_cert

  • Value type is path
  • There is no default value for this setting.

SSL certificate path

ssl_enable

  • Value type is boolean
  • Default value is false

Enable SSL (must be set for other ssl_ options to take effect).

ssl_key

  • Value type is path
  • There is no default value for this setting.

SSL key path

ssl_key_passphrase

  • Value type is password
  • Default value is nil

SSL key passphrase

ssl_verify

  • Value type is boolean
  • Default value is false

Verify the identity of the other end of the SSL connection against the CA. For input, sets the field sslsubject to that of the client certificate.

tags

  • Value type is array
  • There is no default value for this setting.

Add any number of arbitrary tags to your event.

This can help with processing later.

type

  • Value type is string
  • There is no default value for this setting.

Add a type field to all events handled by this input.

Types are used mainly for filter activation.

The type is stored as part of the event itself, so you can also use the type to search for it 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.
