The standard Python logging levels are all options: `critical`, `fatal`, `error`, `warning`, `info`, `debug`, `notset`.



The name of the [opentelemetry-python](https://github.com/open-telemetry/opentelemetry-python) logger used for

this may change in future, so there is a second environment variable, `PYTANGO_TELEMETRY_SDK_LOGGER_NAMES`, which

can be set to a comma-seperated list of logger names.  Defaults are used if the environment variable is empty or

not set.



(As at version 1.35.0, opentelemetry-python

[does not support](https://github.com/open-telemetry/opentelemetry-python/issues/1059) its own `OTEL_LOG_LEVEL`

environment variable).
