The official uWSGI distribution includes a plugin adding Nagios-friendly output.
To monitor, and eventually get warning messages, via Nagios, launch the following command, where node
is the socket (UNIX or TCP) to monitor.
uwsgi --socket <node> --nagios
You can set a warning message directly from your app with the :func:`uwsgi.set_warning_message` function. All ping responses (used by Nagios too) will report this message.
