Python logger dynamic filename

Question

I want to configure my Python logger in such a way so that each instance of logger should log in a file having the same name as the name of the logger itself.

e.g.:

Answer 1

The approach used in the above solution is correct, but that has issue of adding duplicate handlers when called more than once. Here is the improved version.

import os
def getLogger(name):
    # logger.getLogger returns the cached logger when called multiple times
    # logger.Logger created a new one every time and that avoids adding
    # duplicate handlers 
    logger = logging.Logger(name)
    logger.setLevel(logging.DEBUG)
    handler = logging.FileHandler(os.path.join('/some/path/', name + '.log'), 'a')
    logger.addHandler(handler)
    return logger

def test(i):
  log_hm = getLogger('healthmonitor')
  log_hm.info("Testing Log %s", i) # Should log to /some/path/healthmonitor.log

test(1)
test(2)
