I'm running Cherrypy as the wsgi server in front of a flask app. How do I start getting statistics about increasing the threading count?  It serves a lot of images that are called simultaneously from a dashboard.

from cherrypy import wsgiserver, log, _cplogging

from test_qd_web_service import app

import logging

import logging.handlers

import sys

from paste.translogger import TransLogger

from repoze.profile.profiler import AccumulatingProfileMiddleware

def run():

    logger = logging.getLogger("accesslog")

    acc = logging.handlers.TimedRotatingFileHandler("test.access.log", when="midnight", backupCount = 7)

    logger.addHandler(acc)

    

    wsgi_app = TransLogger(app, logger_name="accesslog", setup_console_handler=False)

    profiled_app = AccumulatingProfileMiddleware(

        wsgi_app,

        log_filename='ws.profile',

        discard_first_request=True,

        flush_at_shutdown=True,

        path='/_profile'

        )

    d = wsgiserver.WSGIPathInfoDispatcher({'/': wsgi_app})

    

    server = wsgiserver.CherryPyWSGIServer(('0.0.0.0', 5050), wsgi_app, numthreads=25)

    

    try:    

        server.start()

    except KeyboardInterrupt:

        server.stop()

                

if __name__ == '__main__':

    run()

I cannot comment on your code but there is a rather undocumented feature in CherryPy 3.2.2 which allows to gather statistics of the server usage.
