監視已設定的快取大小
此事件型監視器會監視已設定的快取限制。
警告狀態
由識別碼為 7688 的事件觸發。原因:DNS 伺服器上的快取大小接近其已設定的限制。遞迴執行緒已觸發事件來將快取大小降低至所設定的限制內。系統可能會經歷短暫的 CPU 尖峰。
重大狀態
由識別碼為 7689 的事件觸發。原因:DNS 伺服器上的快取大小接近其已設定的限制。逾時執行緒已開始將快取大小降低至所設定的限制內。系統可能會經歷短暫的 CPU 尖峰。
狀況良好狀態可能由識別碼為 7690 的事件觸發:DNS 伺服器上的快取大小已降低至其已設定的限制內。
DNS 伺服器將會自動進行清理,如有需要,將會排清快取,使其降至設定的限制之內。使用者可能會因此經歷 CPU 尖峰。如果此錯誤的發生頻繁太高,則請檢查所設定的快取限制。如果該限制對您的部署而言太低,請做相應的變更。
