codec

edit
  • Value type is codec
  • Default value is "plain"

The codec used for output data. Output codecs are a convenient method for encoding your data before it leaves the output, without needing a separate filter in your Logstash pipeline.

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

Command line to launch and pipe to

message_format

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

The format to use when writing events to the pipe. This value supports any string and can include %{name} and other dynamic strings.

If this setting is omitted, the full json representation of the event will be written as a single line.

edit

  • Default value is 10

Close pipe that hasn’t been used for TTL seconds. -1 or 0 means never close.
