logging remove / inspect / modify handlers configu

Question

How can I remove / inspect / modify handlers configured for my loggers using the fileConfig() function?

For removing there is Logger.removeHandler(hdlr) method, but how do I get the handler in first place if it was configured from file?

Answer 1

logger.handlers contains a list with all handlers of a logger.

Answer 2

Another approach might be to use a JSON or YAML config file which gets loaded into a dictionary which you can then view/manipulate before it's passed to the logger.config.

import yaml
import logging.config

with open (LOG_CONFIG, 'rt') as f:
   config=yaml.safe_load(f)
   config['handlers']['error_file_handler']['filename']='foo'
logging.config.dictConfig(config)
