OpenTelemetry Magento2 auto-instrumentation

Please read https://opentelemetry.io/docs/instrumentation/php/automatic/ for instructions on how to install and configure the extension and SDK.

Auto-instrumentation hooks are registered via composer, and spans will automatically be created for:

Http::launch() - creates the root HTTP server span, attaches request attributes, records the response status code, propagates response headers, and records exceptions.
Bootstrap::terminate() - creates a Bootstrap::terminate span and records any terminating exception.
FrontController::dispatch() - creates a FrontController.dispatch span around front controller routing.
Action::dispatch() - creates a span named from the Magento full action name, or unknown when it is unavailable.
ActionInterface::execute() - creates an ActionInterface.execute span around action execution.
Manager::dispatch() - creates EVENT: {event name} spans for Magento event dispatches, with unknown as a fallback.
InvokerInterface::dispatch() - creates OBSERVER: {observer name} spans for observer execution, with unknown as a fallback.
Template::fetchView() - creates TEMPLATE: {template path} spans for template rendering and records rendering exceptions.
View::renderLayout() - creates a LAYOUT: layout_render span around layout rendering and records rendering exceptions.

In addition to spans, Http::launch() also records the http.server.request.duration metric with request metadata and response/error attributes.

The extension can be disabled via runtime configuration:
