Try this for your logging setting and see if it helps.
Notice disable_existing_loggers is True and I added a default '' to the loggers.
LOGGING = {
'version': 1,
'disable_existing_loggers': True,
'formatters': {
'standard': {
'format': '%(asctime)s %(levelname)s %(name)s %(message)s'
},
},
'handlers': {
'default': {
'level':'DEBUG',
'class':'logging.handlers.RotatingFileHandler',
'filename': '/home/linuxuser/mani/f/logs/msg.log',
'maxBytes': 1024*1024*5, # 5 MB
'backupCount': 5,
'formatter':'standard',
},
'request_handler': {
'level':'DEBUG',
'class':'logging.handlers.RotatingFileHandler',
'filename': 'logs/django_request.log',
'maxBytes': 1024*1024*5, # 5 MB
'backupCount': 5,
'formatter':'standard',
},
},
'loggers': {
'': {
'handlers': ['default'],
'level': 'DEBUG',
'propagate': True
},
'django.request': { # Stop SQL debug from logging to main logger
'handlers': ['request_handler'],
'level': 'DEBUG',
'propagate': False
},
}
}

Answer 2

A few questions.
Are you seeing anything in /home/linuxuser/mani/f/logs/msg.log?
Or just not the log message you wanted? If you aren't seeing anything
Do you have permission to write to that file?
In your case 2, you shouldn't need this in the settings.py file.
import logging
import logging.handlers
from django.conf import settings
logging.basicConfig()
you should just need the LOGGING tuple. For more info on configuration see the django documentation.
