Django logs print statemeents are not writing to file - django

In django i am adding logging and storing logs to file. It is writing to files the infor and errors
But not print statements.
No print statements are coming.
I wants to write all including print statements also.
LOGGING = {
'version': 1,
'formatters': {
'verbose': {
'format': '%(levelname)s %(asctime)s %(module)s %(process)d %(thread)d %(message)s'
},
'simple': {
'format': '%(levelname)s %(message)s'
},
},
'handlers': {
'console': {
'level': 'DEBUG',
'class': 'logging.StreamHandler',
'formatter': 'simple'
},
'file': {
'level': 'DEBUG',
'class': 'logging.FileHandler',
'filename': 'logs.log',
'formatter': 'simple'
},
},
'loggers': {
'django': {
'handlers': ['file'],
'level': 'DEBUG',
'propagate': True,
},
}
}
Please have a look, how i can achive this.

If you want to have a proper logging system, you should change all the print to logger.info to log your statements.
Have a look here.

How to log Django warnings and errors to log file in Production?

What I want to achieve is that warning and errors that happen in production (i.e. DEBUG=False) are logged into to a rotating log file.
I tried this
LOGGING = {
'version': 1,
'disable_existing_loggers': True,
'handlers': {
'file': {
'level': 'WARNING',
'class': 'logging.FileHandler',
'filename': 'staging.log',
},
},
'loggers': {
'': {
'handlers': ['file'],
'level': 'WARNING',
'propagate': True,
},
'django': {
'handlers': ['file'],
'level': 'WARNING',
'propagate': True,
},
'django.request': {
'handlers': ['file'],
'level': 'WARNING',
'propagate': True,
},
},
}
However, the above logs everything, not just messages of log level WARNING and above.
You can follow the django logger here.
In your views.py:
import logging
logger = logging.getLogger(__name__)
then you can record using logger.error() or logger.warning() or logger.info().
It will create a logger file in your main project directory and it will list out all the logging details.
See this:
LOGGING = {
'version': 1,
'disable_existing_loggers': False,
'formatters': {
'verbose': {
'format': '{levelname} {asctime} {module} {process:d} {thread:d} {message}',
'style': '{',
},
'simple': {
'format': '{levelname} {message}',
'style': '{',
},
},
'handlers': {
'logfile': {
'level': 'DEBUG',
'class': 'logging.handlers.RotatingFileHandler',
'filename': "yourproject_name.log",
'maxBytes': 100000,
'backupCount': 2,
'formatter': 'verbose',
},
},
'loggers': {
'django': {
'handlers': ['logfile'],
'level': 'INFO',
'propagate': True,
},
'apps': {
'handlers': ['logfile'],
'level': 'DEBUG',
'propagate': True,
},
},
}

Elastic APM: How to turn off logging for django

flushing due to time since last flush 9.060s > max_flush_time 9.060s
I 'm getting tone of those message in django debug.
I tried changing to their default setting
LOGGING = {
'version': 1,
'disable_existing_loggers': True,
'formatters': {
'verbose': {
'format': '%(levelname)s %(asctime)s %(module)s %(process)d %(thread)d %(message)s'

'class': 'logging.StreamHandler',
'formatter': 'verbose'
}
},
'loggers': {
'django.db.backends': {
'level': 'ERROR',
'handlers': ['console'],
'propagate': False,
},
'mysite': {
'level': 'WARNING',
'handlers': ['elasticapm'],
'propagate': False,
},
# Log errors from the Elastic APM module to the console (recommended)
'elasticapm.errors': {
'level': 'ERROR',
'handlers': ['console'],
'propagate': False,
},
},
}
Still getting lots of logs.

Django Logger with User info

I'm just curious. Is it possible to put User info within the formatters info in LOGGING config in setting.py?
Right now I just put that info in the message to log but maybe there's a way to set it in formatters argument.
This is my LOGGING configuration right now:
LOGGING = {
'version': 1,
'disable_existing_loggers': False,
'formatters': {
'verbose': {
'format': '%(levelname)s %(asctime)s %(module)s %(process)d %(thread)d %(message)s'
},
'simple': {
'format': '[%(asctime)s] %(levelname)s [%(funcName)s] %(message)s'
}
},
'handlers': {
'console': {
'level': 'DEBUG',
'class': 'logging.StreamHandler',
'formatter': 'simple'
},
'file': {
'level': 'DEBUG',
'class': 'logging.FileHandler',
'filename': BASE_DIR + '/logs/uca_{:%d_%m_%Y}.log'.format(time.now()),
'formatter': 'simple'
}
},
'loggers': {
'ucalog': {
'handlers': ['file'],
'level': 'DEBUG',
'propagate': True
}
}
}
I haven't seen anything similar in django's documentation and I think it would be usefull to get records of WHO did WHAT.
try this :
'format': '[%(asctime)s] %(levelname)s [%(funcName)s] - %(username)s: %(message)s'
logging.basicConfig(format=format)
logger.info(message, extra={'username' : request.user.username})

store data in the log files

I am using Django 1.8 for a project. I have kept the logs in the settings as :
LOGGING = {
'version': 1,
'disable_existing_loggers': False,
'formatters': {
'verbose': {
'format': '%(levelname)s %(asctime)s %(module)s \
%(process)d %(lineno)d %(thread)d %(message)s'
},
'simple': {
'format': '%(levelname)s %(lineno)d %(message)s'
},
},
'handlers': {
'null': {
'level': 'DEBUG',
'class': 'logging.NullHandler',
'formatter': 'verbose'
},
'console': {
'level': 'DEBUG',
'class': 'logging.StreamHandler',
'formatter': 'verbose'
},
'console_simple': {
'level': 'DEBUG',
'class': 'logging.StreamHandler',
'formatter': 'simple'
},
'mail_admins': {
'level': 'ERROR',
'class': 'django.utils.log.AdminEmailHandler',
'formatter': 'verbose'
},
'requests': {
'level': 'INFO',
'class': 'logging.FileHandler',
'filename': '/var/log/request.log',
'formatter': 'verbose'
},
},
'loggers': {
'django': {
'handlers': ['null'],
'propagate': True,
'level': 'INFO',
},
'django.request': {
'handlers': ['console'],
'level': 'WARNING',
'propagate': False,
},
'logger': {
'handlers': ['requests'],
'level': 'INFO',
'propagate': False,
},
},
}
I get errors regularly as Bad Request, so I want to see what data is sent through the front-end to the function calls.
I want to know if there is a way so that I can store the data sent by the front-end to the functions?Any advances will be appreciated.
You can add the loggers to the log the content in log file.
'logfile': {
'level':'DEBUG',
'class':'logging.handlers.RotatingFileHandler',
'filename': SITE_ROOT + "/logfile",
'maxBytes': 50000,
'backupCount': 2,
'formatter': 'standard',
},
Take a look at Simple Log to File example for django 1.3+

Why does my Django 1.3 logging setup cause all messages to be output twice?

My Django 1.3 logging setup causes all log messages to be output twice. I've read that importing settings.py two or more times has caused this problem in the past, but Django 1.3 has new logging features, and I don't think I'm importing settings.py twice anywhere.
settings.py config:
LOGGING = {
'version': 1,
'disable_existing_loggers': False,
'formatters': {
'simple': {
'format': '%(levelname)s: %(message)s'
},
},
'handlers': {
'console': {
'level': 'DEBUG',
'class': 'logging.StreamHandler',
'formatter': 'simple',
},
},
'loggers': {
'custom': {
'handlers': ['console'],
'level': 'DEBUG',
},
}
}
Code:
import logging
log = logging.getLogger('custom')
log.debug('message1')
log.debug('message2')
Output:
DEBUG: message1
DEBUG:custom:message1
Thanks for your help.
Have you tried setting propagate = False? Along with disable_existing_loggers = True?
LOGGING = {
'version': 1,
'disable_existing_loggers': True,
'formatters': {
'simple': {
'format': '%(levelname)s: %(message)s'
},
},
'handlers': {
'console': {
'level': 'DEBUG',
'class': 'logging.StreamHandler',
'formatter': 'simple',
},
},
'loggers': {
'custom': {
'handlers': ['console'],
'level': 'DEBUG',
'propagate': False,
},
}
}
You might want to try 'disable_existing_loggers': True?
I've been suffered by the same issue. And I fixed it by redirecting the root logs to a file, and project logs to both the file and the console.
I grep my code, and could not find anywhere basicConfig() exists, also tried to set disable_existing_loggers to True, It doesn't help, finally solved the problem by set a file logger. I guess it maybe a problem by design in some cases.
LOGGING = {
'version': 1,
'disable_existing_loggers': False,
'formatters': {
'simple': {
# exact format is not important, this is the minimum information
'format': '%(asctime)s %(name)-12s %(lineno)d %(levelname)-8s %(message)s',
},
},
'handlers': {
'console': {
#'level': 'INFO',
'class': 'logging.StreamHandler',
'formatter': 'simple',
},
# Add Handler for mail_admins for `warning` and above
'mail_admins': {
'level': 'ERROR',
'class': 'django.utils.log.AdminEmailHandler',
},
'file': {
#'level': 'INFO',
'class': 'logging.FileHandler',
'formatter': 'simple',
'filename': os.path.join(os.path.dirname(PROJECT_ROOT), 'crawler.admin.log'),
},
},
'loggers': {
# root logger
'': {
'level': 'INFO',
'handlers': ['file', 'mail_admins'],
},
'scrapy': {
'level': 'WARNING',
'handlers': ['console', 'mail_admins'],
'propagate': False,
},
'crawleradmin': {
'level': 'INFO',
'handlers': ['console', 'file', 'mail_admins'],
# required to avoid double logging with root logger
'propagate': False,
},
},
}
