Prefect is super cool! I have a logging question (after reading through: https://docs.prefect.io/latest/concepts/logs/?h=logging) We have this logger defined but are not seeing logs in UI - any way to easily set from this?

def get_logger(name):
    logger = logging.getLogger(name)
    logger.setLevel(logging.DEBUG)  # Or any level you want

    # Create a console handler
    ch = logging.StreamHandler()
    ch.setLevel(logging.DEBUG)  # Or any level you want

    # Create a formatter
    formatter = logging.Formatter("%(asctime)s - %(name)s - %(levelname)s - %(message)s")

    # Add the formatter to the handler
    ch.setFormatter(formatter)

    # Add the handler to the logger
    logger.addHandler(ch)

    return logger

hi @Ashe! have you checked out configuring this via this setting?

PREFECT_LOGGING_SETTINGS_PATH=PosixPath('${PREFECT_HOME}/logging.yml')

Hi @Ashe we had a similar problem. The key is to add an

APILogHandler

to your logger — this will pipe its outputs to the UI just like a

run_logger

.

from prefect.logging.handlers import APILogHandler

def get_logger(name):
     # your code
     api_handler = APILogHandler()
     logger.addHandler(api_handler)

     return logger

@Robert Banick how did you mute this when not running a flow locally?

I’m not sure I understand what you mean by “mute” — you mean turn off the logger?

since

get_logger

is global for me, when I’m not running a flow and testing other parts of the code base locally I get

attempted to send logs to the API without a flow run id. The API log handler can only send logs within flow run contexts unless the flow run id is manually provided.

wondering if you found a clever way to only add this handler when it knows its a “flow”

ah yeah I don’t do much testing of flows locally (our problems are usually server-side) so I haven’t encountered this

perhaps this might help? otherwise, feel free to share more about the scenario where you want to disable logs
