ListenUDP source IP for single datagram

[Doug Royal <em...@dougroyal.com>]

In the ListenUDP processor, when using the "FlowFile per Datagram" option,
I'd like to be able to track the message source IP.

I've dug through the source code, and there isn't a way to do this now.

I was wondering if anyone had an interest in, or concerns about this
feature?

Thanks,
Doug

Doug,

Did a quick scan through and it does look like we're not exposing
this.  I agree with you that this would be cool/useful.  It looks like
this line is the one that is throwing away this useful context today:

https://github.com/apache/nifi/blob/master/nifi-commons/nifi-socket-utils/src/main/java/org/apache/nifi/io/nio/DatagramChannelReader.java#L52

The return type of the receive call is a SocketAddress of the sender
and that is precisely what it looks like you'd want.  That would make
for a great flow file attribute to add.

Thanks
Joe
