Translate filter plugin

Elastic Stack Logstash
2

If you want to enrich with more complex data you can always format the string as JSON and then use a JSON filter to parse it:

input {
  generator {
    lines => ['test']
    count => 1
  } 
} 

filter{
  translate {
    field => "message"
    dictionary => {
      "test" => '{"a":1,"b":2}'
    }
  }

  json {
    source => "translation"
    remove_field => ["translation"]
  }
}

output { stdout { codec => rubydebug} }
