Network Programming in Elixir and Erlang: B3.0 code change in XStats.Reporter
In init/1 change the following line:
dest_port = Keyword.fetch!(options, :dest_port)
to:
dest_port = Keyword.fetch!(options, :server_port)
The problem surfaces on page 144, Manual Testing on the following call:
{:ok, reporter} = XStats.Reporter.start_link(server_port: 9034)
