The configuration object used to provide only configuration for the meter and tracer providers. Now it can be used to load any configuration value stored in an environment variable that starts with OPENTELEMETRY_PYTHON_ whose characters match with [A-Z_]. All this is explained with greater detail in the documentation. The documentation also includes a section that gathers and explains all the current environment variables that are meaningful for OpenTelemetry Python. In this way, the end user can have them all listed in one single place. If in the future, more environment variables are used, then they should be added there and documented accordingly.

Fixes #515

Looks good! I think there's still some rough edges around using environment variables exclusively to drive providers, but maybe we can talk through it more another time?

Also I might look at pydantic: 3.6+ support only, but it does the env variable -> config conversion you have written by hand: https://pydantic-docs.helpmanual.io/usage/settings/

This looks great! I was looking for a way to configure something like blacklisted host names for flask applications and seems like this would be the way to go.

Generally speaking looks good to me.

I'm wondering if we should relax the restrictions on the names, I think a variable called OPENTELEMETRY_PTYHON_MY_VALUE_2 should be valid.

def test_property(self):
with self.assertRaises(AttributeError):
Configuration().tracer_provider = "new_tracer_provider"

def test_slots(self):
with self.assertRaises(AttributeError):
Configuration().xyz = "xyz" # pylint: disable=assigning-non-slot

def test_getattr(self):
Configuration().xyz is None

Is it missing the assertion?

Iep, 😅 fixing...

This is a configuration manager for OpenTelemetry. It reads configuration
values from environment variables prefixed with
``OPENTELEMETRY_PYTHON_`` whose characters are only all caps and underscores.
The first character after ``OPENTELEMETRY_PYTHON_`` must be an uppercase

I think this sentence is not needed as the sentence before already implies it.

Fixed.


1. ``OPENTELEMETRY_PYTH_SOMETHING``
2. ``OPENTELEMETRY_PYTHON_something``
3. ``OPENTELEMETRY_PYTHON_SOMETHING_2_AND__ELSE``

Is there any specific reason to not support this one?

Fixed, any valid variable name is supported now.

It'd be nice to have other env variables here to show that it's generic.
