 **prom2teams** is a Web server built with Python that receives alert notifications from a previously configured [Prometheus Alertmanager](https://github.com/prometheus/alertmanager) instance and forwards it to [Microsoft Teams](https://teams.microsoft.com/) using defined connectors.

+For production environments you should prefer using a WSGI server. [uWSGI](https://uwsgi-docs.readthedocs.io/en/latest/)
+dependency is installed for an easy usage. Some considerations must be taken to use it:
+
+The binary `prom2teams_uwsgi` launches the app using the uwsgi server. Due to some incompatibilities with [wheel](https://github.com/pypa/wheel)
+you must install `prom2teams` using `sudo pip install --no-binary :all: prom2teams` (https://github.com/pypa/wheel/issues/92)

 Consider not provide `chdir` property neither `module` property.
 
+Also you can set the `module` file, by doing a symbolic link: `sudo mkdir -p /usr/local/etc/prom2teams/ && sudo ln -sf /usr/local/lib/python3.5/dist-packages/usr/local/etc/prom2teams/wsgi.py /usr/local/etc/prom2teams/wsgi.py` (check your dist-packages folder)
+
+Another approach is to provide yourself the `module` file [module example](bin/wsgi.py) and the `bin` uwsgi call [uwsgi example](bin/prom2teams_uwsgi)

 **Note:** default log level is DEBUG. Messages are redirected to stdout. To enable file log, set the env APP_ENVIRONMENT=(pro|pre)
