Thanks for bringing this up. That's interesting and a bit dangerous<br>
request, especially if misconfigured.<br>
<br>
What exactly would you like to see in the log? Content of PRL or ORO<br>
options, i.e. a list of options being requested or the actual content of<br>
all options the client sent in its messages?<br>
<br>
Take a look at the loggers we currently have:<br>
<a href="https://kea.readthedocs.io/en/latest/arm/logging.html#the-name-string-logger" rel="noreferrer" target="_blank">https://kea.readthedocs.io/en/latest/arm/logging.html#the-name-string-logger</a><br>
<br>
In particular, you may look at kea-dhcp{4,6}.packets. If you're trying<br>
to debug a client that his packets are rejects,<br>
kea-dhcp{4,6}.bad-packets is something to look at. Also, there's<br>
kea-dhcp4.options logger.<br>
<br>
If none of those work for you, can you open an issue in gitlab?<br>

Thanks,<br>
