I am trying to use Django logger by giving the following settings:
LOGGING = {
'version': 1,
'disable_existing_loggers': False,
'filters': {
'require_debug_false': {
'()': 'django.utils.log.RequireDebugFalse',
},
'require_debug_true': {
'()': 'django.utils.log.RequireDebugTrue',
},
},
'formatters': {
'simple': {
'format': '[%(asctime)s] %(levelname)s %(message)s',
'datefmt': '%Y-%m-%d %H:%M:%S'
},
},
'handlers': {
'logfile': {
'level': 'INFO',
'filters': ['require_debug_false','require_debug_true'],
'class': 'logging.FileHandler',
'filename': '/tmp/django-log.log',
'formatter': 'simple'
},
},
'loggers': {
'user_activity': {
'handlers': ['logfile',]
},
}
}
and then using it in the view like following:
user_logger = logging.getLogger('user_activity')
...
user_logger.info("opened page")
Although Django creates file django-log.log, it doesn't write to it.
Is there a problem with my settings?
Thanks
In the handler filters, you can use either django.utils.log.RequireDebugFalse or django.utils.log.RequireDebugTrue, not both. They are mutually exclusive.
You would need to set the level of the logging when you create the log object using logging.getLogger(name):
Try this before writing to the logger:
user_logger.setLevel(logging.INFO)

I have configuration dictionary for python scripts that I import from another module like below
LOG_CONFIG = {
'version': 1,
'disable_existing_loggers': False,
'loggers': {
'': {
'handlers': ['consoleHandler', 'fileHandler'],
'level': 'DEBUG'
}
},
'handlers': {
'consoleHandler': {
'level': 'INFO',
'formatter': 'consoleFormatter',
'class': 'logging.StreamHandler',
'stream': 'ext://sys.stdout',
},
'fileHandler': {
'level': 'INFO',
'formatter': 'fileFormatter',
'class': 'logging.FileHandler',
'mode': 'w',
}
},
'formatters': {
'fileFormatter': {
'format': '%(asctime)s - %(levelname)s - %(name)s - %(module)s - %(funcName)s - %(message)s',
'datefmt': '%Y-%m-%d %H:%M:%S',
'class': 'logging.Formatter'
},
'consoleFormatter': {
'format': 'UAC_API>> %(levelname)s - %(message)s'
},
},
}
I want log filename to be variable. When loading configuration from a file, I used:
logging.config.fileConfig(config_file,
defaults={'logfilename': logfullpath},
disable_existing_loggers=False)
Where logfullpath is path to the log file.
But defaults={'logfilename': logfullpath} does not work with dictConfig (comparing to logging.config.fileConfig has just one agument). Would anybody help me with that please?
Found a workaround if anyone has the same problem. Since the LOG_CONFIG is the dictionary I expanded it like can be seen below (added filename:logfullpath as key value pair for fileHandler). Then I used it as argument for dictConfig.
LOG_CONFIG['handlers']['fileHandler']['filename'] = logfullpath
logging.config.dictConfig(LOG_CONFIG)
I'm trying to connect my django project logs to Azure Application Insights using OpenCensus. The middleware for montirong requests works well but I also want to send telemetry logs (not just requests) to Azure. Here is my django LOGGING configuration :
LOGGING = {
'version': 1,
'disable_existing_loggers': False,
'formatters': {
'verbose': {
'format': '%(asctime)s %(levelname).3s %(process)d %(name)s : %(message)s',
},
'simple': {
'format': '%(asctime)s %(levelname)-7s : %(message)s',
},
},
'filters': {
'require_debug_false': {
'()': 'django.utils.log.RequireDebugFalse',
}
},
'handlers': {
'console': {
'class': 'logging.StreamHandler',
'formatter': 'verbose',
},
'azure': {
'formatter': 'simple',
'class': 'opencensus.ext.azure.log_exporter.AzureLogHandler',
'connection_string': 'InstrumentationKey=XXXX-XXXX-XXXX-XXXX'
},
'mail_admins': {
'level': 'ERROR',
'filters': ['require_debug_false'],
'class': 'django.utils.log.AdminEmailHandler'
}
},
'loggers': {
'': {
'level': os.environ.get('LOGLEVEL', 'INFO'),
'handlers': ['console', 'azure'],
},
'devdebug': {
'handlers': ['console'],
'level': 'INFO',
'propagate': False,
},
'django': {
'handlers': ['console', 'mail_admins'],
'level': os.environ.get('LOGLEVEL', 'INFO'),
'propagate': False,
}
},
}
Without 'azure' handler in my root logger config, everything works fine. With 'azure' handler, the server starts but doesn't work : I am unable to connect to it. I really don't know what is happening as it doesn't show me unusual logs (even with LOGLEVEL=DEBUG).
My handler configuration should be good as I can receive logs in Azure (when I run any manage command). Even when I run manage runsslserver localhost:53215, I receive logs but it is like my server is not running when I try to reach it.
I have setup the logging via settings and have it working (although not using runsslserver. I have set the connection_string as an environment variable.
The problem I am having is that the 'django' logger does not work in production. All other loggers are sending messages but not that one??? I have a classic case of it works on my machine and our dev servers but not prod... FML!!

I'm trying to integrate logging with loki in my django app like this:
handler = logging_loki.LokiHandler(
url="http://localhost:3100/loki/api/v1/push",
tags={"app": "django", "env": ENV},
version="1",
)
LOGGING = {
'version': 1,
'disable_existing_loggers': False,
'formatters': {
'standard': {
'format': '[%(asctime)s] {%(module)s} [%(levelname)s] - %(message)s',
'datefmt': '%d-%m-%Y %H:%M:%S'
},
},
'handlers': {
'console': {
'level': 'INFO',
'class': 'logging.StreamHandler',
'formatter': 'standard',
}
},
'loggers': {
'': {
'handlers': ['console', handler], # this doesnt work
'level': 'DEBUG',
'propagate': True,
# 'name': ENV
}
}
}
What do I need to change so that django uses this custom handler? I tried just referencing the handler object in the logging dict but that didn't need to be the right approach.
I also tried this:
LOGGING_CONFIG = None
logging.config.dictConfig(LOGGING)
logging.getLogger(__name__).addHandler(handler)
but that's not sending any logs to loki
Try this:
LOGGING = {
'version': 1,
'disable_existing_loggers': False,
'formatters': {
'standard': {
'format': '[%(asctime)s] {%(module)s} [%(levelname)s] - %(message)s',
'datefmt': '%d-%m-%Y %H:%M:%S'
},
},
'handlers': {
'console': {
'level': 'INFO',
'class': 'logging.StreamHandler',
'formatter': 'standard',
},
'loki': {
'level': 'INFO',
'class': 'logging_loki.LokiHandler',
'url': "http://localhost:3100/loki/api/v1/push",
'tags' {"app": "django", "env": ENV},
'version': "1",
},
},
'loggers': {
'': {
'handlers': ['console', 'loki'],
'level': 'DEBUG',
'propagate': True,
}
}
}
Specifically, you have to:
Define you handler in the handlers dictionary in the LOGGING setting. The configuration here is used to specify the initialisation arguments for the handler.
Then assign this handler using its key (loki in the example I've given above) to the logger(s) you want it to handle.
My Logging settings is like below:
LOGGING = {
'version': 1,
'disable_existing_loggers': True,
'formatters': {
'standard': {
'format' : "[%(asctime)s] %(levelname)s [%(name)s:%(lineno)s] %(message)s",
'datefmt' : "%d/%b/%Y %H:%M:%S"
},
},
'handlers': {
'null': {
'level':'DEBUG',
'class':'django.utils.log.NullHandler',
},
'logfile': {
'level':'DEBUG',
'class':'logging.handlers.RotatingFileHandler',
'filename': LOG_ROOT + "/logfile",
'maxBytes': 50000,
'backupCount': 2,
'formatter': 'standard',
},
'console':{
'level':'INFO',
'class':'logging.StreamHandler',
'formatter': 'standard'
},
},
'loggers': {
'django': {
'handlers':['console'],
'propagate': True,
'level':'WARN',
},
'django.db.backends': {
'handlers': ['console'],
'level': 'DEBUG',
'propagate': False,
},
'home': {
'handlers': ['console', 'logfile'],
'level': 'DEBUG',
},
}
}
I am calling it like
import logging
log = logging.getLogger('home')
log.error("Hey there it works!!")
getting error No handlers could be found for logger "home"
Seems I am missing something during configuration, also went through the past SQ questions to figure it out, but couldn't figure it out.
What is wrong, any clue?
Thanks in advance.
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,
},
},
}
