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!" })

Fluent uses second-precision for events, so you will not see sub-second precision on events processed by this codec.

• Value type is boolean
• Default value is false

Enables sub-second level precision while encoding events.

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

Define the target field for placing the decoded values. If this setting is not set, data will be stored at the root (top level) of the event.

For example, if you want data to be put under the logs field:

input {
  tcp {
    codec => fluent {
      target => "[logs]"
    }
    port => 4000
  }
}
