我有一堆ELBs在多個區域設置,我通常想知道服務器在其中一個服務器上掉轉時的情況。我在UnhealthyHostCount
上設置了一個報警across all lbs
。這種方式一般效果很好,但是當一臺服務器出現故障時,報警告訴我的唯一情況是某臺服務器掉了一圈,沒有任何關於發生位置或者服務器的信息:CloudWatch可以提供服務器或elb的詳細信息嗎?
Alarm Details:
- Name: ServerOutOfRotation
- Description: Some server falls out of rotation
- State Change: OK -> ALARM
- Reason for State Change: Threshold Crossed: 1 datapoint (1.0) was greater than or equal to the threshold (1.0).

- AWS Account: 1234
Threshold:
- The alarm is in the ALARM state when the metric is GreaterThanOrEqualToThreshold 1.0 for 60 seconds.
Monitored Metric:
- MetricNamespace: AWS/ELB

有沒有辦法讓這個提供,或者我必須在每個負載平衡器上設置單獨的警報來獲取這些信息?
