# RollDice
The following example uses a basic [Phoenix](https://www.phoenixframework.org/)
web application. For more elaborate examples, see [examples](/docs/instrumentation/erlang/examples/).
To start your Phoenix server:
* Run `mix setup` to install and setup dependencies
* Start the opentelemetry collector and Jaeger front-end with `docker-compose up -d`
* Set your service name `export OTEL_SERVICE_NAME="roll_dice"`
* Start Phoenix endpoint with `mix phx.server` or inside IEx with `iex -S mix phx.server`
To generate and view traces:
* Visit the new API endpoint with `curl http://localhost:4000/api/rolldice` or in your browser
* Visit [`localhost:16686`](http://localhost:16686) to see the traces in Jaeger
For more information on the OpenTelemetry instrumentation in this example, check out the guide for getting started with [OpenTelemetry](https://opentelemetry.io/docs/instrumentation/erlang/getting-started/)
## How did we get here?
To begin, use the `phx` generator to create a new project. To keep things simple we'll leave out the database and html for now with the `--no-ecto` and `--no-html` flags.
In a real app, you'll probably want to include ecto configured for your preferred database with the `--database` flag (`postgres` by default).
```shell
mix phx.new --no-ecto --no-html roll_dice
```
### Rolling The Dice
Now we'll add an API endpoint that will let us roll the dice and return a random
number between 1 and 6.
To start, we'll add a route to the `/api` scope in your router
```elixir
# lib/roll_dice_web/router.ex
scope "/api", DiceGameWeb do
pipe_through :api
get "/rolldice", DiceController, :roll
end
```
Then we'll create a new file in the controllers folder for that module. We told
the router that we will define a roll function, so we'll do that. It will return
a `200` response code and the result of a `dice_roll` function, which we will
emit a span for. We also want to set the value of the generated roll as an
attribute on the span.
```elixir
# lib/roll_dice_web/controllers/dice_controller.ex
defmodule DiceGameWeb.DiceController do
use DiceGameWeb, :controller
require OpenTelemetry.Tracer, as: Tracer
def roll(conn, _params) do
send_resp(conn, 200, roll_dice())
end
defp roll_dice do
Tracer.with_span("roll_dice") do
roll = Enum.random(1..6)
Tracer.set_attribute("roll.value", roll)
to_string(roll)
end
end
end
```
If you point your browser/curl/etc. to [`localhost:4000/api/rolldice`](http://localhost:4000/api/rolldice) you should get a random number in response.
Ready to run in production? Please [check our deployment guides](https://hexdocs.pm/phoenix/deployment.html).

This module defines the test case to be used by
tests that require setting up a connection.
Such tests rely on `Phoenix.ConnTest` and also
import other functionality to make it easier
to build common data structures and query the data layer.
Finally, if the test case interacts with the database,
we enable the SQL sandbox, so changes done to the database
are reverted at the end of every test. If you are using
PostgreSQL, you can even run database tests asynchronously
by setting `use RollDiceWeb.ConnCase, async: true`, although
this option is not recommended for other databases.
