Configure access logging for your AWS load balancers to improve monitoring and analysis capabilities. This plan ensures a robust setup by guiding you through assessing existing resources, configuring logging to S3 buckets, and verifying that logs are correctly generated and accessible.
Select AWS Region: Guide the user to choose the correct AWS region for configuration. This step ensures all resources are managed within the chosen region.
List Load Balancers: Retrieve and display all existing Application, Network, and Classic Load Balancers in the selected region to identify which are available for logging configuration.
Gather LB Details: Collect essential information about the load balancer, including identifier, type, and preferred S3 bucket for access logs. Guide users on choosing whether to use an existing bucket or create a new one.
Verify LB Logging Support: Check if the selected load balancer supports logging. Alert users if a Network Load Balancer is chosen, as it does not support access logging.
Create S3 Bucket for Logs: Conditional on user preference, create a new S3 bucket specifically for access logs, ensuring appropriate regional configuration.
Set ELB Write Permissions: Develop and apply an S3 bucket policy, authorizing AWS ELB to store logs in the designated bucket.
Enable LB Logging: Implement logging on ALB/CLB by altering attributes to ensure logs are recorded and stored as specified. This step is skipped for NLB.
Generate Test Traffic: Simulate HTTP traffic to confirm load balancer logging configuration by sending multiple requests to the endpoint, ensuring logs are triggered.
Verify Logs in S3: List generated access logs in the specified S3 bucket to verify successful configuration and storage of logs, affirming operational logging processes.
