@Marvin can you give me an example of using prefect logging?

Ah, the sweet sound of logs being written. Here's an example of using Prefect logging: First, create a

logging.yml

configuration file to customize Prefect logging. Use Prefect's default logging configuration as a starting point by copying its text into a new file. Note that this log configuration requires Prefect 2.6 or later. Next, place your logging configuration in a file named

logging.yml

in Prefect's home directory. The default Prefect home directory varies by operating system: -

/home/<username>/.prefect

on Linux -

/Users/<username>/.prefect

on macOS -

C:\Users\<username>\.prefect

on Windows You can override any logging configuration by setting an environment variable or Prefect Profile setting using the syntax

PREFECT_LOGGING_[PATH]_[TO]_[KEY]

, with

[PATH]_[TO]_[KEY]

corresponding to the nested address of any setting. For example, to change the default logging levels for Prefect to DEBUG, you can set the environment variable

PREFECT_LOGGING_LEVEL="DEBUG"

. You may also configure the "root" Python logger. Here's an example of how to start a Prefect agent with a custom log file:

bash
$ PREFECT_LOGGING_HANDLERS_FILE_FILENAME=/var/log/prefect-agent1.log prefect agent start -q default

This will start the Prefect agent and log its output to

/var/log/prefect-agent1.log
