Installation
def deps do
[
{:opentelemetry_phoenix, "~> 1.0.0-rc"}
]
end
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:
defmodule MyApp.Endpoint do
use Phoenix.Endpoint, otp_app: :my_app
...
plug Plug.Telemetry, event_prefix: [:phoenix, :endpoint]
...
end
The Phoenix endpoint.ex template can be used as a reference
