如何从 AWS CloudWatch 应用程序 ELB 获取延迟指标？
How to get latency metric from AWS CloudWatch Application ELB?
有什么方法可以从 AWS/ApplicationELB 命名空间获取延迟吗？我知道它在 AWS/ELB 命名空间中可用，但我需要它用于 AWS/ApplicationELB，因为这是我使用的。
ELB 上的延迟指标与 ALB 上的 TargetResponseTime 指标相当。
ELB 延迟定义： (source)
The total time elapsed, in seconds, from the time the load balancer
sent the request to a registered instance until the instance started
to send the response headers.
ALB TargetResponseTime 定义： (source)
The time elapsed, in seconds, after the request leaves the load
balancer until a response from the target is received. This is
equivalent to the target_processing_time field in the access logs.
