識別目標組中的AWS不正常主機

Question

我有多個在AWS ALB后面運行的targetGroups。 此外，我設置了cloudwatch警報來監視這些目標組的運行狀況。 每當該組中的目標生成不健康主機警報時，AWS都會發送電子郵件提醒我該組中的目標遭受了不健康。 但是，警報和電子郵件不會通知我該目標組的哪個實例不正常。

有沒有一種方法或解決方案可以實施並找出導致該問題的目標人群？

# Trigger the lambda function when an EC2 instance is terminated
resource "aws_cloudwatch_event_rule" "instance_terminated" {
  name = "ChefCleanup-InstanceTerminated-rule"
  description = "Capture each EC2 instance termination"
  event_pattern = <<PATTERN
  {
    "source": [ "aws.ec2" ],
    "detail-type": [ "EC2 Instance State-change Notification" ],
    "detail": {
      "state": [ "terminated" ]
    }
  }
PATTERN
}

# Set event target to call the lambda
resource "aws_cloudwatch_event_target" "instance_terminated" {
  rule      = "${aws_cloudwatch_event_rule.instance_terminated.name}"
  target_id = "chef-cleanup-lambda"
  arn      = "${aws_lambda_function.chef_cleanup.arn}"
}
