[英]Using TimedRotatingFileHandler logging with a logging.config
我正在嘗試使用帶有logging.config文件的TimedRotatingFileHandler進行測試,沒有任何復雜但它應該每隔10秒滾動到一個新的日志文件中。
但是我得到以下內容
Traceback (most recent call last):
File "testLogging.py", line 6, in <module>
logging.config.fileConfig(logDir+'logging.conf')
File "C:\Python26\Lib\logging\config.py", line 84, in fileConfig
handlers = _install_handlers(cp, formatters)
File "C:\Python26\Lib\logging\config.py", line 159, in _install_handlers
h = klass(*args)
File "C:\Python26\Lib\logging\handlers.py", line 195, in __init__
raise ValueError("You must specify a day for weekly rollover from 0 to 6 (0
is Monday): %s" % self.when)
ValueError: You must specify a day for weekly rollover from 0 to 6 (0 is Monday)
: WHEN='S'
python非常簡單,只是設置了一個不斷記錄的無限循環
import logging
import logging.config
logDir = "./logs/"
logging.config.fileConfig(logDir+'logging.conf')
logger = logging.getLogger('root')
while 1==1:
logger.info('THIS IS AN INFO MESSAGE')
和配置文件
[loggers]
keys=root
[logger_root]
level=INFO
handlers=timedRotatingFileHandler
[formatters]
keys=timedRotatingFormatter
[formatter_timedRotatingFormatter]
format=%(asctime)s %(name)-12s %(levelname)-8s %(message)s
datefmt=%m-%d %H:%M
[handlers]
keys=timedRotatingFileHandler
[handler_timedRotatingFileHandler]
class=handlers.TimedRotatingFileHandler
level=INFO
formatter=timedRotatingFormatter
args=('./logs/log.out', 'when=\'S\'', 'interval=10', 'backupCount=5')
正如您所看到的那樣設置為'S'而不是'W',就像錯誤消息似乎表明的那樣。
編輯:根據下面的答案,日志配置中的正確語法是
args=('./logs/log.out', 'S', 10, 5, None, False, False)
args=('./logs/log.out', 'when=\'S\'', 'interval=10', 'backupCount=5')
看起來不對。 試試這個
args=('./logs/log.out', when='S', interval=10, backupCount=5)
或者可能這樣
args=('./logs/log.out','S',10,5)
