Amazon S3 logging

• https://docs.aws.amazon.com/AmazonS3/latest/userguide/logging-with-S3.html

Amazon S3 allows users to enable or disable logging. If enabled, the logs are stored in Amazon S3 buckets which can then be analyzed. These logs contain useful information such as:

• Date and time of access to requested content
• Protocol used (HTTP, FTP, etc.)
• HTTP status codes
• Turnaround time
• HTTP request message

• Terraform resource: aws_s3_bucket_logging

Limitations:

• The destination bucket must be in the same AWS Region and AWS account as the source bucket.
• S3 buckets that have S3 Object Lock enabled can't be used as destination buckets for server access logs
• Your destination bucket must not have a default retention period configuration.

Recomendations:

• we recommend that you use a bucket policy instead of ACLs.
