Discrepancy between Cloudfront Usage Report and Cloudfront metrics in Cloudwatch


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

Cloudwatch: Enter image description here

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

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!
