It seems like building a thermostat that has data logging as to how often it comes on and for how long would be the best route, because what else is there to track? you can't really track air exchange rates or heat loss all you can do is track energy used and if your furnace is using that fuel then tracking how often it comes on and for how long will give you the info you are asking for.
