What is the appropriate path if the interface specified does not exist?
Before adjusting, this currently returns 1.0.0.0. Would it make sense, should
the interface not be found, to omit the inclusion of the attribute and value?

> Project: Apache NiFi MiNiFi
> Issue Type: Bug
> Components: C++, Extensions
> Reporter: Randy Gelhausen
>
> Downstream consumers of data produced by nifi-minifi agents often need to
> route FlowFiles based on hostname or IP of the machine running the agent.
> nifi-minifi-cpp needs an AppendHostInfo processor which reads its' hostname
> and IPv4 address for a specified network interface.
