Hi,

The documentation gives a few exmaples in the section about 
logging:

https://kea.readthedocs.io/en/kea-2.0.2-doc/arm/logging.html

There's not just _one_ log you can tune to DEBUG, but multiple. 
I've
found that it's not just enough to set the parent logger to DEBUG, 
but
to set all the interesting logger names to the relevant logging 
level.

Good luck!

PS. Make sure to test your configuration changes with the builtin
tester: kea-dhcp4 -t path/to/config
