Python logging（配置实现）

定义我们的日志模块

定义统一入口，读取配置文件

#mylog.pyimport loggingimport logging.configdef getLogger(name='root'):    CONF_LOG = "/home/stephen/openstack/demo/log/log/logging.conf"    logging.config.fileConfig(CONF_LOG)    return logging.getLogger(name) 

日志配置文件
我们配置了三种类型的日志，root， test1, test2,我们在使用是只需指明我们所使用的类型。

#logging.conf[loggers]keys=root,test1,test2[handlers]keys=rotatingFileHandler,test1Handler,test2Handler[formatters]keys=simpleFmt[logger_root]level=DEBUGhandlers=rotatingFileHandler[logger_test1]level=DEBUGhandlers=test1Handlerqualname=test1propagate=0[logger_test2]level=DEBUGhandlers=test2Handlerqualname=test2propagate=0 [handler_rotatingFileHandler]class=handlers.RotatingFileHandlerlevel=DEBUGformatter=simpleFmtargs=("/tmp/default.log", "a", 20*1024*1024, 10)[handler_test1Handler]class=handlers.RotatingFileHandlerlevel=DEBUGformatter=simpleFmtargs=("/tmp/test1.log", "a", 20*1024*1024, 10) [handler_test2Handler]class=handlers.RotatingFileHandlerlevel=DEBUGformatter=simpleFmtargs=("/tmp/test2.log", "a", 20*1024*1024, 10) [formatter_simpleFmt]format=%(asctime)s %(pathname)s(%(lineno)d): %(levelname)s %(message)s

我们的测试模块

我们在模块中的调用方式如下，就是指明我们的日志名称，也即是指明我们将这个模块的日志打到那个文件。

#test1.pyimport mylog as loggingLOGGER = logging.getLogger("test1")class TestLog1(object):    """docstring for TestLog1"""    def __init__(self, arg=None):        super(TestLog1, self).__init__()        self.arg = arg        LOGGER.info("test1 info mesage will wirte in test1.log")        LOGGER.warning("test1 warning mesage will wirte in test1.log")        LOGGER.debug("test1 debug mesage will wirte in test1.log")

#test2.pyimport mylog as loggingLOGGER = logging.getLogger("test2")class TestLog2(object):    """docstring for TestLog2"""    def __init__(self, arg=None):        super(TestLog2, self).__init__()        self.arg = arg        LOGGER.info("test2 info mesage will wirte in test2.log")        LOGGER.warning("test2 warning mesage will wirte in test2.log")        LOGGER.debug("test2 debug mesage will wirte in test2.log")

测试入口

测试的入口，我们执行python test.py即可
在这里我们并没有指定日志类型，也就是说没有指明我们要把日志打到那个文件，当然就会到我们定义好的默认文件root日志中：

#test.pyimport mylog as loggingimport test1import test2LOG = logging.getLogger(__name__)def main():    LOG.info("test info message:test1.TestLog1()")    test1.TestLog1()     LOG.info("test info message: test1.TestLog2()")    test2.TestLog2()if __name__ == '__main__':    main()
