EMSメッセージがドロップされる原因は何ですか

環境

ONTAP 9

回答

• イベントはEMS抑制アルゴリズムによって抑制されました。
• イベント処理システムは、複数のアルゴリズムを実装してイベントを調整します。
• 抑制されたイベントの情報には event status show コマンドを使用してください

ontap91::> set diag -confirmation off; event status show -message-name security.invalid.login -ins

追加情報

• Use event config show を使用して、イベント抑制アルゴリズムが有効（"on"）か無効（"off"）かを判別します。

• 抑制アルゴリズムの詳細については、event show-suppressiondiagコマンドを参照してください。
