The notifications are the sensor data of each baremetal node, each node
will have a file with the sensor data as metrics in the Prometheus format.
Since Prometheus is pull-based the Flask application wlil merge the content
of all files to provide to the Prometheus when necessary.

like and this can be done before moving the project or something
to be done trough reviews after the project is moved.
