Hi,

How do we configure log settings so that every day generates new log file and also based on max file size?

I am able to use "RotatingFileHandler" to rotates files based on max file size with following settings.

'handlers': {
        'file': {
            'level': 'DEBUG',
            'backupCount': 10,  # how many backup file to keep, 10 days
            'class': 'logging.handlers.RotatingFileHandler',
            'filename': '/home/iness/logs/vconnect.log',
            'maxBytes': 1024*1024*1,  # 1MB
            'backupCount': 10,
            'formatter': 'standard'
        },
    }

i get a problem with the 'formatter' : 'standard'

Watching for file changes with StatReloader

Exception in thread django-main-thread:

The above exception was the direct cause of the following exception:
