使用 Amazon 監控 OpenSearch 服務事件 EventBridge
Amazon OpenSearch 服務與 Amazon 集成， EventBridge 以通知您某些事件會影響您的域。來自 AWS 服務的事件會以近乎即時 EventBridge 的方式傳送到。同樣的事件也被發送到 Amazon CloudWatch 活動，Amazon EventBridge 的前身。您可編寫簡單的規則，來指示您在意的事件，以及當事件符合規則時所要自動執行的動作。可以自動觸發的動作如下：
-
調用一 AWS Lambda 個函數
-
叫用 Amazon EC2 執行命令
-
將事件轉傳至 Amazon Kinesis Data Streams
-
激活 AWS Step Functions 狀態機
-
通知 Amazon SNS 主題或 Amazon SQS 佇列
如需詳細資訊，請參閱 Amazon EventBridge 使用者指南 EventBridge中的開始使用 Amazon。

GC 不足
OpenSearch 當最大 JVM 超過 70％ 且最大值和最小值之間的差異小於 30％ 時，服務會發送此事件。這可能表示 JVM 無法在工作負載的記憶體回收週期期間回收足夠的記憶體。這可能會導致回應速度越來越慢，延遲時間越來越高；在某些情況下，甚至節點會因為運作狀態檢查逾時而中斷。為了確保最佳的叢集穩定性，請減少叢集的流量或調整網域，以提供足夠的記憶體來處理工作負載。
