See past load balancer target health check failure reason

0

We know how to check the health and reason for failure of a target in a network load balancer, but we haven't figured out how to find out the reason for a past health check failures. Is there a way to see this in the cloud watch metrics?

Hello.

You can check the number of target instances that failed the health check by looking at things like "UnHealthyHostCount," but I don't think you can check the cause of the failure.
Therefore, I think it is difficult to identify the cause of past health check failures from CloudWatch metrics.
