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

Answer 1

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.

Answer 2

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")
