Hi @garvord,
In OH2, there is no openhab.cfg file anymore.
You configure your system via the Paper UI (install bindings, add things, etc) and you can also modify the text based config files in /etc/openhab2/ (e.g. /etc/openhab2/services/mqtt.cfg or /etc/openhab2/items/default.items)
To manage logging, take a look here: http://docs.openhab.org/administration/logging.html & Taming openHAB 2 Logging
Example: to set log level to TRACE to the MQTT binding:
- Enter into the Karaf console (
ssh openhab@localhost -p 8101
with password habopen) - log:list
- log:set TRACE org.openhab.mqtt
- log:set TRACE org.openhab.io.transport.mqtt
In general, take a look at http://docs.openhab.org to see how OH2 works

Good Luck,
