Elastic Load Balancing access logs
The access logs for Elastic Load Balancing capture detailed information for all requests made to your load
balancer and stores them as log files in the Amazon S3 bucket that you specify. Each log contains details such
as the time a request was received, the client’s IP address, latencies, request path, and server responses. You
can use these access logs to analyze traffic patterns and to troubleshoot your back-end applications. For more
