Python 2.4.3: ConfigParser.NoSectionError: No section: 'formatters'

Question

Trying to use a logging configuration file to implement TimedRotatinigFileHandler.

Just won't take the config file for some reason.

Any suggestions appreciated.

x.py:

import logging
import logging.config
import logging.handlers

logging.config.fileConfig("x.ini")

MyLog = logging.getLogger('x')

MyLog.debug('Starting')

x.ini:

[loggers]
keys=root

[logger_root]
level=NOTSET
handlers=trfhand

[handlers]
keys=trfhand

[handler_trfhand]
class=handlers.TimedRotatingFileHandler
when=M
interval=1
backupCount=11
formatter=generic
level=DEBUG
args=('/var/log/x.log',)

[formatters]
keys=generic

[formatter_generic]
class=logging.Formatter
format=%(asctime)s %(levelname)s %(message)s
datefmt=

Traceback (most recent call last):
  File "x.py", line 5, in ?
    logging.config.fileConfig("x.ini")
  File "/usr/lib/python2.4/logging/config.py", line 76, in fileConfig
    flist = cp.get("formatters", "keys")
  File "/usr/lib/python2.4/ConfigParser.py", line 511, in get
    raise NoSectionError(section)
ConfigParser.NoSectionError: No section: 'formatters'

Thanks

The error message is strictly accurate but misleading.

The reason the "formatters" section is missing, is because the logging module can't find the file you passed to logging.config.fileConfig.

Try using an absolute file path.

Thank you very much! The exception message was not very helpful. Creating a file called logging.ini solves the problem. – Gang Su Nov 07 '15 at 00:27

Yes, @ekhumoro was right. It seems that logging expects an absolute path. Python team should change this error message to something more readable; it just cannot see my file, not because the config file itself is wrong.

I managed to solve this by defining a BASE_DIR variable in a config file and import it as the prefix of the path, just as Django does. And, remember to create the log file's parent dir(s) if they are not created.

I define the path and the logger in config.py:

import os
BASE_DIR=os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

import logging
import logging.config
logging.config.fileConfig(os.path.join(BASE_DIR, 'utils', 'logger.conf')) # the `logger.conf` locates under 'myproject/utils/'
logger = logging.getLogger("mylog") # 'mylog' should exist in `logger.conf` in the logger part

In other modules:

from config import logger
...

logger.info("Your loggings modules should work now!! - WesternGun")
