Degraded Minutes 閾值監視。此監視設定為從介面取得過去 15 分鐘間隔內的衰退分鐘數計數。
透過 SNMP GET 查詢的物件識別碼 (OID) 詳細資料如下:
dsx1IntervalDM | 1.3.6.1.2.1.10.18.8.1.11 | 衰退分鐘是指一分鐘內估計的錯誤率超過 1E-6 但未超過 1E-3。衰退的分鐘數的判定方式是,收集所有的可用秒數,移除任何嚴重錯誤的秒數,將結果分組為 60 秒群組,而如果累計錯誤在群組中的秒數內超過 1E-6,便將該 60 秒群組 (分鐘) 計為衰退 這是在 RFC 1406 中定義 |
這會在以下情況發生:
此監視在於測量每分鐘的錯誤率。如果其他錯誤率較高,則衰退的分鐘數將開始增加。
基本疑難排解步驟列舉如下:
查看其他錯誤計數以判定造成錯誤分鐘數的原因。
提供監視的閾值。如此可將應用程式調整為較適合於您的環境。但請注意不要將閾值調得過高,以免漏掉重要事件。
