Data Explorer
=============

The Data Explorer is a tool that allows to capture and record the data produced by all the sensors in the currently deployed infrastructure.
It is particularly useful to train ML models which require the collection of a huge amount of data

By enabling the data explorer, the following resources are created in Azure:

#. **Data Export** in Azure IoT Central to forward data to an Event Hub
#. **Event Hub namespace** and **instance** in Azure Portal to collect and make available the incoming messages from the Data Export

Once the Data Explorer is enabled, a command is displayed, which can be used to run a server in a docker container,
that listens to all incoming messages from the Event Hub.

The application will be accessible at `http://localhost:8080`, this can be used to start recording data, and export them once finished.

It is also possible to disable the Data Explorer, action which deletes all the allocated resources on Azure.
