4章自動計装
OpenTelemetryのAPI設計では、テレメトリーの計装はライブラリを計装するのにもっとも適した人物、 つまりコードの開発者やメンテナーの手に委ねられています。 これは理想的なパターンですが、常に適用できるわけではありません。 アプリケーションのオーナーは、計装されたリリースにパッケージの依存関係をアップグレードする必要があります。 すぐにセットアップして便利に使えるユビキタスなテレメトリーを提供するという使命に忠実であり続けるために、 OpenTelemetryプロジェクトは人気のあるライブラリやフレームワークに対して自動的に計装を追加する一連のパッケージを提供しています。 本章では、自動計装の仕組みと構成する方法について、Javaアプリケーションを例に探っていきます。
