Overview
Each line of a log exposes the raw line, but it also has method accessors for all the fields of the logged request.
The list of supported log line fields are listed in the S3 documentation: docs.amazonwebservices.com/AmazonS3/2006-03-01/LogFormat.html
line = log.lines.first
line.remote_ip
# => '72.21.206.5'
If a certain field does not apply to a given request (for example, the key
field does not apply to a bucket request), or if it was unknown or unavailable, it will return nil
.
line.operation
# => 'REST.GET.BUCKET'
line.key
# => nil
