Interface Fields

The interface fields are used to record ingress and egress interface information when reported by an observer (e.g. firewall, router, load balancer) in the context of the observer handling a network connection. In the case of a single observer interface (e.g. network sensor on a span port) only the observer.ingress information should be populated.
