CDNの運用保守を行う場合、業務の特殊性から、qos解析のために集中センターにログを転送することは現実的ではないため、Nginxのログを5分ごとに切り出し、Pythonプログラムを通じてhttpコードの分布を計算し、Zabbixを通じて1台のマシンでNginx qosの監視を実現する方法です。ZabbixデータベースLastvalueの集約により、CDN全体のトラフィック、qosデータなどを監視することができます。これは、rsync + hadoで、一般的に5分程度の遅延で問題を発見することができます。ZabbixのデータベースLastvalueの集計は、全体のCDNのトラフィック、qosのデータなどを監視することができますので、5分程度で問題の発見の一般的な遅延は、nginxのログを計算するためにrsync + hadoop + hiveを使用すると、また、投稿以下のNginxのログの使用の分析の様々な次元のより詳細な分析を得ることができます！以下は、Nginxログに使用した分析スクリプトです：
