俺も死んだ(ﾁｰﾝ
今頃なのか今更なのか知りませんが、Elasticstackに手を出し始めました。
柔軟性が高いのはいいけど、その柔らかさに殺されそうでまぢつらたんです(´；ω；｀)
ちなみに構成は、
CentOS6
elastic 6.x
です。
さて、今回問題のケースでは、ログをfilebeatで取得して、logstashに流し込み、elasticsearchに書き込む構成を取りました。
そして、複数サーバーのログを集約させたいので、各サーバーにfilebeatを設置する、という形にしました。
図（？）にするとこんな感じ？ずれてたらごめんなさい
[FB]―[LS]―[ES]
[FB]／
これで動かしたけれども、elasticsearchのほうにIndexがさっぱり作られません。おかしいと思って/var/log/logstash/logstash-plain.logを見ると、以下のエラーがいっぱい書かれてました。

長すぎ！
まぁ要点は「Error: Cannot assign requested address」だと思います。
この時、2つのfilebeatが設定していたlogstashの宛先ポートはどちらも5044でした。
冷静になって考えたら、1つのポートを奪い合う状態はまずいので、片方のfilebeatのポートを5055に変更してやり直してみたら、普通に動きました！(∩´∀｀)∩ﾜｰｲ
単純にポートの競合はやめましょうって話でした。よくよく考えると恥ずかしいｗ
