Discrepancy between Cloudfront Usage Report and Cloudfront metrics in Cloudwatch

Question

I am trying to get monthly usage statistics of Cloudfront and I am seeing massive discrepancy between CloudFront > Reports & analytics > Usage > Reports and the Cloudwatch metrics for Cloudfront.

Cloudfront: ![Enter image description here](/media/postImages/original/IMClCw98IDRtarSu3ilW1Y6Q)

Cloudwatch: ![Enter image description here](/media/postImages/original/IMxI3Q7actTvmRasdNOaOeBA)

What is the source of this difference? How can I get the same result for total usage in Cloudwatch as Cloudfront report?

Answer

CloudWatch Metrics Insights currently has the following limits:
* Currently, you can query only the most recent three hours of data.

See https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/cloudwatch-metrics-insights-limits.html.

If you changed your graph view from Number to Line for example it tells you this. Seems really misleading it doesn't tell you for Number!
