amazon-web-services - 如何从 AWS CloudWatch 应用程序 ELB 获取延迟指标？

Question

有什么方法可以从 AWS/ApplicationELB 命名空间获取延迟？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。

Answer 1

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.
