The information captured in flow logs includes information about allowed and denied traffic, source and destination IP addresses, ports, protocol number, packet and byte counts, and an action (accept or reject). All services and instances currently available in EC2-Classic have comparable services available in the Amazon VPC environment. When you enable ClassicLink on an EC2-Classic instance, the instance retains and uses its existing private IP address to communication with resources in a VPC.
