How to get online YARP stats

[sergiobortsov]

What should we add or change to make your life better?

it would be great to have the way to get some online YARP stats like current assigned requests per destination, queue (if there is some queue functionality), etc

Why is this important to you?

I'm building the tool to analyze a load balancer stats and then managing the quantity of destinations based on that.

Thanks

See #1124. Once you get the destinations you can look here for request counts:
https://github.com/microsoft/reverse-proxy/blob/1f27ecf4e1b23fd44bc9106f6765c65944caa271/src/ReverseProxy/Model/DestinationState.cs#L54

YARP does not have a queue, though the underlying HttpClient might. I don't think that's visible anywhere.
