オプション1を採用する。
例として、既存のSqlAgentImpl#queryメソッドの中で startTImeの取得は行っている(PERFORMANCE_LOG.isDebugEnabled() == trueの場合のみ)
また、finally 句の中で
formatElapsedTime(startTime, Instant.now(getSqlConfig().getClock()))という形でendTimeを計算している
この2つの変数をうまく利用できないか検討してください

オプション1を採用し、既存のstartTimeとformatElapsedTimeの仕組みを活用する方針に更新しました。
具体的には:
ExecutionContextにstartTime/endTimeフィールドとgetExecutionTime()メソッドを追加SqlAgentImpl内で既存のパフォーマンスログ用startTime取得時にExecutionContextにも設定- finally句で
endTimeを設定し、常に実行時間を取得可能にする
この方針により、既存のコードを最大限活用しつつ、Micrometerのメトリクス収集にも対応できます。(304647c)

実装を開始しました。以下を完了しました:
現在、テストの一部が失敗していますが、これは cleanInsert() によるデータセットアップ時の SQL 実行もメトリクスにカウントされてしまうためです。テストを修正中です。 コミット: 39c468b (ExecutionContext 拡張), 8fe701a (MicrometerEventSubscriber 実装) |
