Step 1: Create an S3 bucket
When you enable access logs, you must specify an S3 bucket for the access log files. The bucket must meet the following requirements.
Step 2: Attach a policy to your S3 bucket
Your S3 bucket must have a bucket policy that grants Elastic Load Balancing permission to write access logs to the bucket. Bucket policies are a collection of JSON statements written in the access policy language to define access permissions for your bucket.
Step 3: Configure access logs
Use the following procedure to configure access logs to capture and deliver log files to your S3 bucket every 60 minutes (the default interval). Note that you can optionally have Elastic Load Balancing create the bucket and add the required policy, if you did not use the previous steps to do so manually.
Step 4: Verify bucket permissions
After access logs are enabled for your load balancer, Elastic Load Balancing validates the S3 bucket and creates a test file to ensure that the bucket policy specifies the required permissions. You can use the S3 console to verify that the test file was created.
Collecting AWS Application Load Balancer Access Logs

Collecting AWS Classic Load Balancer Access Logs
The AWS Sensor automatically detects Classic Load Balancer access logs after you have enabled them in AWS. After they're enabled in AWS, all you need to do is to enable the log collection job in USM Anywhere.
Short description
To use access logs with your load balancer, the load balancer and the Amazon S3 bucket must be in the same account. You must also attach a bucket policy to the Amazon S3 bucket that allows ELB permission to write to the bucket. Depending on the error message you receive, see the related resolution section.
Additional troubleshooting
If you verified your S3 bucket policy and configuration and still can't view logs, verify that the load balancer is receiving traffic. To verify whether the load balancer is receiving traffic, check the ActiveConnectionCount and RequestCount metrics.
