各ポッド全体で一貫したログ形式を持つために、各コンポーネントはイベントロギングに共通のインターフェイスを使用します。ログは JSON 形式を使用するため、すべてのデータが 1 行に表示されます。ログは INFO レベルで書き込まれるため、デフォルトではこのレベルを無効にして、必要な場合に有効にできます。
ログは、対応するログレベルが INFO、DEBUG、または TRACE に設定されている場合に書き込まれます。ただし、メッセージの要求または応答フィールドは、ログレベルが DEBUG または TRACE に設定されている場合にのみ入力されます。
Debug レベルが有効になっている場合のサンプルログsgw-service-0 [INFO] [Transaction.go:1595] [transaction.event.sgw-service]
