Allow failing fast for auto-instrumentation problems

[phillipuniverse]

What problem do you want to solve?

If there's an exception in an auto-instrumentation, we currently log the exception and continue. I would like an option to fail faster and immediately re-raise the exception to the caller.

Here's where we currently swallow any instrumentation exceptions:

opentelemetry-python-contrib/opentelemetry-instrumentation/src/opentelemetry/instrumentation/auto_instrumentation/__init__.py

Lines 121 to 135 in 7bd0895

	def initialize():
	"""Setup auto-instrumentation, called by the sitecustomize module"""
	# prevents auto-instrumentation of subprocesses if code execs another python process
	if "PYTHONPATH" in environ:
	environ["PYTHONPATH"] = _python_path_without_directory(
	environ["PYTHONPATH"], dirname(abspath(__file__)), pathsep
	)
	try:
	distro = _load_distro()
	distro.configure()
	_load_configurators()
	_load_instrumentors(distro)
	except Exception: # pylint: disable=broad-except
	_logger.exception("Failed to auto initialize OpenTelemetry")

With this, there's no way to say, fail startup of my service if there's an instrumentation problem.

Describe the solution you'd like

I'd like to be able to re-raise instrumentation exceptions and fail startup if there's a failure in this case:

from opentelemetry import autoinstrumentation

autoinstrumentation.initialize()
