Why the bucket metrics are showing me only 4.7 GB of objects stored while I have 123 GB stored in an S3 bucket as Glacier Deep Archive?

Note that the Amazon S3 monitoring metrics are recorded once per day. Therefore, these metrics might not display the most updated information. However, CloudWatch monitors your AWS resources and applications in real time. Also, S3 console and Storage Lens use base 2 conversion (/1024) to report storage metrics, and CloudWatch by default uses base 10 conversion (/1000).
