Telemetry helpers for AzureSDK operations.

Events

• [:azure_sdk, :request, :start] — pipeline span started
• [:azure_sdk, :request, :stop] — pipeline span finished with duration
• [:azure_sdk, :request, :attempt] — emitted before each HTTP attempt
• [:azure_sdk, :auth, :sign] — emitted when a request is signed
• [:azure_sdk, :retry] — emitted on retry backoff

• [:azure_sdk, :blob, :put | :get | :delete | ...] — service operations

Attach a handler:

:telemetry.attach(
  "ex-azure-logger",
  [:azure_sdk, :request, :stop],
  fn _event, measurements, metadata, _config ->
    IO.inspect({measurements, metadata}, label: "azure_sdk request")
  end,
  nil
)
