Medical Examination - application for register health check callbacks and represent their state via HTTP.

1. Add medex to your list of dependencies in mix.exs:

   def deps do
     [{:medex, github: "xerions/medex"}]
   end

2. Ensure medex is started before your application:

   def application do
     [applications: [:medex]]
   end

Register new check callback:

Medex.register "db", fn ->
    case :erlang.phash2(:erlang.now, 3) do
      0 -> :ok
      1 -> :warning
      2 -> :critical
    end
  end

and get state

$ curl -v http://localhost:4000/health/db

Medex suports pushing health check statutes to Consul. It is disabled by default but you can turn it on:

# use consul, false by default
config :medex, consul: true

# which service name will be using for consul health-checks (optional)
config :medex, service_id: "service_example"

And ensure start of consul application.
