ALB and NLB Access Logs

Ingest Application and Network Load Balancer access logs into Bronto — client IP, request details, target, latency, and response code — from an S3 bucket.

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.

Recommended method

S3 Log Forwarder — enable access logging on each load balancer with a destination bucket, then point the Bronto forwarder Lambda at the bucket. New log objects are picked up via S3 event notifications and streamed into Bronto.

See Ingesting AWS Data into Bronto for the full service-to-method mapping.
