Logging

オープンソースのログ管理

Elastic Stackは、最も人気のあるオープンソースのログ管理のプラットフォームです。その理由をご紹介しましょう。

Elastic Stackで楽々ログ管理を体験してみる。今すぐトライ

簡単に始められる

Elastic Stackには、一般的なデータソースにそのまま使えるダッシュボードがあらかじめ用意されています。FilebeatとWinlogbeatでログを送信してElasticsearchにインデックス、数分後にはKibanaで可視化されています。ジャンプして今すぐインストールできます。 必要なモジュールが見つからない場合は、新たに開発することも、コミュニティを活用することもできます。これがオープンソースの良いところです。

リアルタイムですべて明らかになる

Elasticsearchを中心とするElastic Stackのおかげで、大規模な環境であっても、素早いレスポンスが期待できます。質問には迅速に答えが返ってきます。

数個でも、数十億のファイルでも

ノートパソコン1台でも、ペダバイトのデータを有する数百台でも同じエクスペリエンスを実現します。頭痛のタネであった再設計は不要です。

貴重なデータを目の届かない場所に置くなんて、と心配しないでください。大切なこと、決定すべきことを、すべて取り込んで、インデックスします。

  • Log into the Elastic Cloud console
To create a cluster, in Elastic Cloud console:
  • Select Create Deployment, and specify the Deployment Name
  • Modify the other deployment options as needed (or not, the defaults are great to get started)
  • Click Create Deployment
  • Save the Cloud ID and the cluster Password for your records, we will refer to these as <cloud.id> and <password> below
  • Wait until deployment creation completes

機械学習で異常検出を自動化

すべてのログメッセージやトランザクションに目を通す必要はありません。重要なもの、または注目に値するものに絞ることができます。

ElasticのMachine Learningは、過去のElasticsearchデータの挙動から自動的にモデルを作成し、リアルタイムで問題を報告します。

あなたの目で確かめてください

大手通信会社のSprintでは、かつてシステム管理者がログを細かくチェックし、シェルスクリプトを実行したり、grepしたりしていました。今はElasticでパフォーマンスの問題のトラブルシューティングを迅速に行えるようになりました。同時に顧客満足度を高め、企業間取引関係を簡略化し、小売りシステムを合理化することにも成功しています。

Elasticをログ管理に利用する事例はこれだけではありません。他のユーザー事例も併せてご覧ください。
