※作成したホストグループに追加しておく
テンプレートの複製
[設定] ⇒ [テンプレート] を選択し、複製対象（Template SNMP Interfaces）のテンプレートを表示して、[すべて複製] を押下、テンプレートを追加（複製）
※作成したホストグループ、ホストを追加しておく
アイテムのプロトタイプ追加
- [設定] ⇒ [テンプレート] 画面で作成したテンプレートの [ディスカバリ] ⇒ [アイテムのプロトタイプ] からアイテムのプロトタイプの作成
※通信量（%）を計算する際の分母となるインターフェースのスピードを取得しておく
トリガーのプロトタイプ追加
- [設定] ⇒ [テンプレート] 画面で作成したテンプレートの [ディスカバリ] ⇒ [トリガーのプロトタイプ] からトリガーのプロトタイプの作成
※（インバウンド通信＋アウトバウンド通信）/インターフェースのスピード×100>80で80％以上のTrafficがある場合、トリガーがひかれる（インバウンド通信＋アウトバウンド通信はアイテム側で8乗算しているのでbpsでの割合となる。）
設定前
- 設定前はインターフェースのステータスのみのトリガーセットとなっている。
設定後
- 1時間程度（ディスカバリルールの初期設定）待つと自動的にアイテムが登録され、同時にトリガーの登録される。
