A security engineer configures VPC Flow Logs and the associated IAM role to log all VPC traffic to a log group in Amazon CloudWatch Logs. After a wait of 10 minutes, no logs are appearing in the log group. The security engineer confirms that traffic is being sent to the VPC.
After additional debugging, the security engineer isolates the problem to the role that is associated with the VPC flow logs.
What could be the reason that the logs are not appearing in CloudWatch Logs?
