uWSGI knows about requests only after accept() and this could happen a lot
of seconds after the request is made on the webserver.
Some month ago i have sent a patch for nginx allowing you to set the time
of request in uwsgi/fastcgi/scgi variables. My ideas was monitoring the
real time taken by the request, but the patch was never accepted (sorry i
do not remember the specific reason). If you plan to use the uWSGI http
router (instead of nginx) this can be easily accomplished, otherwise
without webserver support wa can do nothing more :(
