Hi all,

I'm attempting to use Raindrops in order to start instrumenting our Unicorn
workloads on Heroku using statsd. I'm a little confused at the numbers it
reports under test.

My primary confusion is that our active number never climbs above the
number of workers we have running. Since we have a large backlog, I
expected to see the total number of accept()'ed clients counted in this
number too. Unfortunately, I only spikes up to the total number of workers
and queued never spikes above 0. I expected the latter as we shouldn't ever
be refusing connections with our large backlog.

If active represents the number of requests that are currently being
serviced and queued represents the number of connections that have yet to
be accept()'ed, is there a way to get out the middle state: requests that
have been accept()'ed but not yet started?

Thanks,
-jp
