similar to the #1548

To find the root cause of the problem, I adjusted the period and length parameters, and noticed that the requests metric data settled down after two minutes.

logs with period: 60, length: 180

In the CloudFront requests metrics, the latest pushed data is unstable and takes some time to stabilize, which can also be observed in the console.

after a while.

Referr to the explanation #865, I add the parameter delay: 120, and obtain the stable data.
