Tested locally, metrics get provided

[tomkerkhove]

Added a ton of nits but for the rest it looks good to me!

Do you have a sample of this in action please?

[ChristianEder]

Resolved your rename remarks. Yes I have an example in action, but its running locally on my machine (the promitor container) and inside my Azure Subscription (the IoT Hub & DPS) - how do you want me to share?

Great thanks!

Maybe the output of the scraping endpoint if you can share it?
