Those options are not typically logged. If you enable debug level 45 or
larger, then both incoming and outgoing packets are going to be logged.
That will include interface-id (18) and remote-id (37). Be aware that it
may be a lot of logs.

Another option you may consider is the forensic logging hook library
logs option 37 if present. See section 13.3.2
(https://jenkins.isc.org/job/Kea_doc/guide/kea-guide.html#idp1376099460).
It does not log interface-id (option 18), but it's a minor change. We
can add it quickly if a customer requests it.

If neither of those approaches work for you, you can develop your own
hook library that would print out those two specific options, along with
whatever extra information you need.

Hope that helps,
