AdyenClient emits :telemetry events on every HTTP request.

Events

EventMeasurementsMetadata
[:adyen_client, :request, :start]system_timemethod, url, body
[:adyen_client, :request, :stop]duration (native)method, url, status, http_status

PCI-sensitive fields (cardNumber, cvv, cvc, expiryMonth, expiryYear, number, holderName) are redacted from body before the event is emitted.

Attaching a handler

# In Application.start/2
:telemetry.attach_many(
  "my-adyen-metrics",
  [
    [:adyen_client, :request, :start],
    [:adyen_client, :request, :stop]
  ],
  &MyApp.AdyenTelemetry.handle/4,
  nil
)
defmodule MyApp.AdyenTelemetry do
  def handle([:adyen_client, :request, :stop], %{duration: dur}, meta, _) do
    ms = System.convert_time_unit(dur, :native, :millisecond)
    MyApp.Metrics.histogram("adyen.request.duration_ms", ms,
      tags: ["method:#{meta.method}", "status:#{meta.http_status}"]
    )
  end

  def handle(_event, _meas, _meta, _cfg), do: :ok
end
