Telemetry handler that creates Opentelemetry spans from Phoenix events.

|
|
top-level supervisor starts.
|
|
|
|
```elixir
|
|
OpentelemetryPhoenix.setup()
|
|
```
|
|
|
|
See the documentation for `OpentelemetryPhoenix.setup/1` for additional options that
|
|
may be supplied.

## Note on phoenix integration
|
|
|
|
`OpentelemetryPhoenix` requires phoenix to use `Plug.Telemetry` in order to correctly trace endpoint calls.
|
|
|
|
The `endpoint.ex` file should look like:
|
|
```Elixir
|
|
defmodule MyApp.Endpoint do
|
|
use Phoenix.Endpoint, otp_app: :my_app
|
|
...
|
|
plug Plug.Telemetry, event_prefix: [:phoenix, :endpoint]
|
|
...
|
|
end
|
|
```
|
|
The [Phoenix endpoint.ex template](https://github.com/phoenixframework/phoenix/blob/v1.6.0/installer/templates/phx_web/endpoint.ex#L39) can be used as a reference
