Interface Fieldsedit

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.

Field Reuseedit

The interface fields are expected to be nested at: observer.egress.interface, observer.ingress.interface.

Note also that the interface fields are not expected to be used directly at the root of the events.
