How do I know if my car is in a DPF regeneration cycle?

How do I know if my car is in a DPF regeneration cycle? It would appear that the engine should not be switched of while this process is taking place but I have never seen any warnings on the dash board to either say this is happening or the DPF filter needs cleaning.

A smell of burning and a lot of heat under the car when you stop. Or, when driving along, a significant increase in the instant fuel consumption on the meter. I think manufacturers should fit a heat-sensitive warning light to tell drivers not to switch off when the DPF is actively regenerating but they won't do that because it would alert drivers to the inconvenience of running a diesel.

I owned an Evoque that had issues with the DPF. But when a diesel flags up that the DPF needs a regen, how long time or distance wise do you have to get it on a motorway/dual carriageway before the fuel...
Does active regeneration of the DPF happen automatically? And should I put additives into the fuel?
Are engine revs raised during DPF regeneration on a Nissan Qashqai?
