Description

edit

The "plain" codec is for plain text with no delimiting between events.

This is mainly useful on inputs and outputs that already have a defined framing in their transport protocol (such as zeromq, rabbitmq, redis, etc).

  • Default value is "UTF-8"

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.

ecs_compatibility

edit
  • Value type is string

  • Supported values are:

    • disabled: plugin only sets the message field
    • v1,v8: Elastic Common Schema compliant behavior ([event][original] is also added)

  • Default value depends on which version of Logstash is running:

    • When Logstash provides a pipeline.ecs_compatibility setting, its value is used as the default
    • Otherwise, the default value is disabled

Controls this plugin’s compatibility with the Elastic Common Schema (ECS).

format

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

Set the message you which to emit for each event. This supports sprintf strings.

This setting only affects outputs (encoding of events).
