Run your uWSGI server with the stats server enabled, Ex.:

uwsgi --module myapp --socket :3030 --stats /tmp/stats.socket

uwsgitop /tmp/stats.socket

To display async core statistics (e.g. when using gevent) or to switch between core statistics display mode, press 'a'.

To refresh the screen super fast, press 'f'.

To quit, press 'q'.
