S3 Cross-Region Replication copies regulated data to another Region.
Notify operators when replication is delayed.
Which method is most appropriate?
Monitor S3 Replication metrics and object Replication Status to detect pending replication work and lag.
Detailed explanation
Pending bytes, operations, and object status expose replication delay.
Pending bytes, operations, and object status expose replication delay.
Total bucket size does not indicate whether replication work is delayed.

Foundation review
Work backlog versus object state
Metrics show aggregate pending work while object status shows a particular object's result.
Capacity is not progress
Bucket size measures stored data, not whether replication has caught up.
