What are we going to build?
---------------------------

We will build a monitoring daemon that monitors web services availability.

The daemon will send the requests to the `example.com <http://example.com>`_ and
`httpbin.org <https://httpbin.org>`_ every couple of seconds. For each successfully completed
response it will log:

- The response code
- The amount of bytes in the response
- The time took to complete the response
