I have

export PREFECT__LOGGING__LEVEL=DEBUG

def main(): 
    logger = get_run_logger()
    logger.warning("warning")
    logger.debug("debug")
    <http://logger.info|logger.info>("info")
    logger.critical("critical")

yet the debug isn’t printing:

14:49:20.921 | WARNING | Flow run 'wonderful-hamster' - warning
14:49:20.921 | INFO    | Flow run 'wonderful-hamster' - info
14:49:20.922 | CRITICAL | Flow run 'wonderful-hamster' - critical

Hi @Bryan Whiting - are you using two underscores when trying to set

PREFECT_LOGGING_LEVEL

? the setting name has single underscores

❯ prefect config set PREFECT__LOGGING__LEVEL="DEBUG"
Unknown setting name 'PREFECT__LOGGING__LEVEL'.

❯ prefect config set PREFECT_LOGGING_LEVEL="DEBUG"
Set 'PREFECT_LOGGING_LEVEL' to 'DEBUG'.

Not Bryan but was following along with a similar issue. For me even setting the correct env variable in code before running my flow I still wasn't getting DEBUG logs. Figured it out, sharing in case it helps anyone else: The env var must be set before

prefect

is imported. Setting it after prefect is imported but before

get_run_logger

is called isn't early enough.

@Nate: https://docs-v1.prefect.io/core/concepts/logging.html#logging-configuration FYI might want to change docs

sure thing! are you using prefect 2 or prefect 1? i assumed you meant prefect 2 but the docs you linked are prefect 1

dang, i’m using 2. i’ll be more careful about lookig for that. thank you!

no problem - lots of things are changing quickly as we shift into the world of prefect 2! happy to help

Thanks. They "look like env vars" so I was just using

os.environ

. Profile indeed seems like the better way to set this!
