Select only one field to output

Elastic Stack Logstash
1

Hello,

I'm trying to setup a logstash configuration. I want to forward the event.original field only on the udp output.

I have a filebeat input, and elasticsearch/udp output. I tried the "codec line" option with "format" but it does not consider the payload %{event.original} as a variable. Here is the configuration sample :

input {
  beats {
    port => 5044
    tags => ["serv1"]
  }

  output {
    if "serv1" in [tags] {
      elasticsearch {
        hosts => ["localhost:9200"]
        index => "serv1"
      }
      udp {
        host => ["192.168.1.1"]
        port => 514
          codec => line {
            format => "%{event.original}"
         }
     }
  }
}

NB : line codec is and format option is working with a syslog input.

Do you have any recommandations ?
