New Puma version has a [nice addition](https://github.com/puma/puma/pull/3517) of metric on busy threads. > busy_threads: running - how many threads are waiting to receive work + how many requests are waiting for a thread to pick them up. this is a "wholistic" stat reflecting the overall current state of work to be done and the capacity to do it.
