ALB and NLB Access Logs
Ingest access logs from Application and Network Load Balancers — client IP, request details, target, latency, and response code.
Application Load Balancers and Network Load Balancers can publish access logs to an S3 bucket. Each entry records the client IP and port, the request line, the chosen target, latency at each hop, and the response code — a comprehensive trail of the traffic that reached your load balancer.
