How to disable loggers from other modules?

Question

I use several modules in my project, however, the modules output lots of logs from the logger, which is annoying. So I turn off the logs by:

boto_log = logging.getLogger("boto")
boto_log.setLevel(logging.CRITICAL)
es_log = logging.getLogger("elasticsearch")
es_log.setLevel(logging.CRITICAL)
urllib3_log = logging.getLogger("urllib3")
urllib3_log.setLevel(logging.CRITICAL)

Though this works, the code looks verbose. Is there any better, simpler way I can do this?

Answer 1

You can disable existing loggers with either logging.config.dictConfig or logging.config.fileConfig.

import logging.config
logging.config.dictConfig({
    'version': 1,
    # Other configs ...
    'disable_existing_loggers': True
})

You can also loop over existing loggers and disable manually.

for name, logger in logging.root.manager.loggerDict.iteritems():
    logger.disabled=True

Answer 2

May be you can refactor it in order to cut some of the boilerplate:

for _ in ("boto", "elasticsearch", "urllib3"):
    logging.getLogger(_).setLevel(logging.CRITICAL)
