What are VPC flow logs?
VPC Flow Logs is a feature that enables you to capture information about the IP traffic going to and from network interfaces within your VPC. Flow log data is then stored using Amazon CloudWatch Logs. And after you’ve created a flow log, you can view and retrieve its log data in Amazon CloudWatch.
Flow logs can be created at three different levels.
