current it does not support marathon http auth

Was scratching my head trying to figure out whats up with this not auto scaling. So I had outputted the stats from the sample function for ALL apps on marathon-lb and noticed that my app I was trying to monitor, the stats are all at 0, but marathon_http_in contains accurate readings. I used blitz.io to stress test the app and it worked, however without the proper stats this method won't work.

Here's the output from a sample query to marathon-lb. Converted to JSON.

is there any particular reason for which it is not possibile to specify a target-rps lower than 1? while dealing with long running tasks having an integer property is quite limiting.

it would be really interesting add options to allow basic authentication in Marathon (user/pass) and to Haproxy

What do you think about it?

I try to add it by myself in my free time...
