How to read uwsgi stats output

I'm on this page http://uwsgi-docs.readthedocs.org/en/latest/StatsServer.html and using uwsgitop but I have no idea how to interpret the output. The docs aren't giving too much away too. So how would one go about understanding this:

Solution

WID -> worker id

% -> percentage of served requests by the worker

PID -> process id of the worker

REQ -> number of managed requests

RPS -> number of current requests handled per second

EXC -> number of raised exceptions

SIG -> number of managed uwsgi signals (NOT unix signals !!!)

STATUS -> can be idle, busy, pause, cheaped or sig

AVG -> average response time for the worker

RSS -> RSS memory (need --memory-report)

VSZ -> address space (need --memory-report)

TX -> transmitted data

RunT -> running time
