注釈

ICMP は、インターネット プロトコル バージョン 4 (IPv4) で使用するメッセージのセットです。 ICMP は、データ パケットの処理中に発生したエラーを報告したり、他のインターネット層機能を実行したりするために、IPv4 ノードによって使用されます。 ICMP バージョン 4 は IETF RFC 792 で定義されています。

アプリケーションで使用できる ICMP バージョン 4 のトラフィック統計の詳細については、クラスのドキュメントを IcmpV4Statistics 参照してください。 IcmpV4Statisticsこのメソッドによって返されるオブジェクトには、オブジェクトが作成された時点の統計が反映されることに注意してください。 この情報は動的に更新されません。
