Yes, Prefect supports logging to a file. You can configure logging through a

logging.yml

file. Prefect allows you to create your own logging configuration by placing a

logging.yml

file in your

PREFECT_HOME

directory or by specifying a custom path using the

PREFECT_LOGGING_SETTINGS_PATH

setting. This configuration file can be used to direct logs to a file, among other things. For more detailed information on configuring logging, you can refer to the Prefect logging documentation. To use a Prefect logger, you can import

get_logger()

from the

prefect.logging

module. This logger can be configured to log to a file as specified in your

logging.yml

. Here's a brief example of how you might set up logging in your flow:

python
from prefect import flow
from prefect.logging import get_logger

@flow
def my_flow():
    logger = get_logger()
    <http://logger.info|logger.info>("This is a log message.")

my_flow()

Ensure your

logging.yml

is correctly configured to direct logs to a file.
