Hi Ádler,
Thank you for your reply.
Can you please review this code before I commit?
"""uWSGIController API Version 0.8.3
Middleware for storing uWSGI statistics into the environ object.

Sounds like you want retrieving statistics from uWSGI's stats server.
http://uwsgi-docs.readthedocs.io/en/latest/StatsServer.html
In order to get that JSON via HTTP requests, your server ".ini" should
receive extra arguments to start an stats server listening to the
specified port and application must be somehow aware of such port
number, which has a side-effect of increasing coupling.
Sincerely,
Adler

Hi,
I would like to access the uWSGI stats API from within Django by
creating a custom WSGI middleware.
Could it be possible to compute the number of requests currently
being used by uWSGI workers in Python/Django ?
Ideally, i could then retrieve the active connections in use in a
standard Django view:
def someview(request):
# retrieve the number of active requests (connections)
connections = request.environ['uwsgi.requests']
What do you think?
