This codec handles fluentd’s msgpack schema.

For example, you can receive logs from fluent-logger-ruby with:

input {
  tcp {
    codec => fluent
    port => 4000

And from your ruby code in your own application:

logger = Fluent::Logger::FluentLogger.new(nil, :host => "example.log", :port => 4000)
logger.post("some_tag", { "your" => "data", "here" => "yay!" })


  • the fluent uses a second-precision time for events, so you will never see subsecond precision on events processed by this codec.



This plugin supports the following configuration options:

Setting Input typeRequired










  • Value type is boolean
  • Default value is true

Disable or enable metric logging for this specific plugin instance by default we record all the metrics we can, but you can disable metrics collection for a specific plugin.

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

Add a unique ID to the plugin configuration. If no ID is specified, Logstash will generate one. It is strongly recommended to set this ID in your configuration. This is particularly useful when you have two or more plugins of the same type, for example, if you have 2 grok filters. Adding a named ID in this case will help in monitoring Logstash when using the monitoring APIs.

output {
 stdout {
   id => "my_plugin_id"
