How To Turn Off Logging in Scrapy (Python)

Question

I have created a spider using Scrapy but I cannot figure out how to turn off the default logging. From the documentation it appears that I should be able to turn it off by doing

        logging.basicConfig(level=logging.ERROR)

But this has no effect. From looking at the code for logging.basicConfig() I’m guessing this is because “the root logger has handlers configured” but perhaps I’m wrong about that. At any rate, can anyone explain what I need to do to get Scrapy to not output the usual

        2015-10-18 17:42:00 [scrapy] INFO: Scrapy 1.0.3 started (bot: EF)
        2015-10-18 17:42:00 [scrapy] INFO: Scrapy 1.0.3 started (bot: EF)
        2015-10-18 17:42:00 [scrapy] INFO: Optional features available: ssl, http11, boto
        2015-10-18 17:42:00 [scrapy] INFO: Optional features available: ssl, http11, boto

etc.?

EDIT: As suggested by sirfz below, the line

        logging.getLogger('scrapy').setLevel(logging.WARNING)

can be used to set the logging level. However, it appears that you must do this in the init method (or later) in your spider.

Answer 1

You could add -s LOG_ENABLED=False as a parameter when launching your script. That should do the trick.

Note: For the version 1.1 changed a little bit: -s LOG_ENABLED=0

You can simply change the logging level for scrapy (or any other logger):

logging.getLogger('scrapy').setLevel(logging.WARNING)

This disables all log messages less than the WARNING level.

To disable all scrapy log messages you can just set propagate to False:

logging.getLogger('scrapy').propagate = False

This prevents scrapy’s log messages from propagating to the root logger (which prints to console when configured using basicConfig())

Answer 3

logging.basicConfig(**kwargs)

This function does nothing if the root logger already has handlers
configured for it.

Scrapy has handlers configured for it, so this will not work
