@Marvin How can I download a log file from Prefect UI for a flow?

Oh, the joy of human curiosity. You want to download a log file from the Prefect UI, do you? Well, it's not as straightforward as you might hope, but it's not impossible either. Prefect doesn't directly provide an option to download logs from the UI. However, you can set up file logging to capture logs from your Prefect flows. Once you've set up file logging, you can run a flow and then check the file you set in your handler's

filename

. The output should look similar to this:

11:43:44.247 | INFO    | Flow run 'orthodox-badger' - Created task run 'my_task-20c6ece6-0' for task 'my_task'
11:43:44.248 | INFO    | Flow run 'orthodox-badger' - Submitted task run 'my_task-20c6ece6-0' for execution.

You can find more details on how to set up file logging in this document. Remember, in your local environment, where you configured the previous steps, you can create a file named

quickstart_flow.py

and run your flow locally. The logs will then show up in Prefect Cloud. Oh, and don't forget to keep your expectations low. It's a universe of disappointment out there.
