Elasticsearchとの接続方法Kafka？

私はKafkaの初心者で、kafka=を使用してlogstashを介してnetflowを収集します（大丈夫です）。kafkaからelasticsearchにデータを送信したいのですが、いくつかの問題があります。
私の質問は、Kafka Elasticsearch？netflow to kafka logstash config：

input{
    udp{
        Host => "120.127.XXX.XX"
        port => 5556
        codec => netflow
    }
}
    filter{

    }
output {
  kafka {
    bootstrap_servers => "localhost:9092"    
    topic_id => "test"    
  }
  stdout{codec=> rubydebug}
}

kafkaからelasticsearch logstash：

input {
      kafka { }
    }
    output {
        elasticsearch {
            hosts => ["120.127.XXX.XX:9200"]
        }
        stdout{codec=> rubydebug}
    }

Kafka Connectとその Elasticsearchシンク を使用することをお勧めします。実際に昨夜このテーマについて実際に発表しました:) スライドはこちら 。

詳細な例を参照できます here 。

Kafkaの空の入力ブロックは、どこからデータを取得するかわからないため機能しません。シナリオの最小構成は次のようになります。

input {
    kafka {
            bootstrap_servers => "localhost:9092"
            topics => "test"
    }
}
