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 in your VPC.
  • Flow log data can be published to CloudWatch Logs (query it using CloudWatch Logs Insights) or S3 (query it using Athena).
  • Flow logs can help you with a number of tasks, such as:
    • Diagnosing overly restrictive security group rules
    • Monitoring the traffic that is reaching your instance
    • Determining the direction of the traffic to and from the network interfaces
  • Flow log data is collected outside of the path of your network traffic, and therefore does not affect network throughput or latency.
