python logging使用

log_file = "./serverchecklog/servertest%s.log"%time.strftime("%Y%m%d%H%M%S")
logging.basicConfig(level=logging.DEBUG,
                    format='[%(asctime)s] %(levelname)-10s %(message)s',
                    filename=log_file)
console = logging.StreamHandler()
console.setLevel(logging.INFO)
formatter = logging.Formatter('[%(asctime)s] %(levelname)-10s %(message)s')
console.setFormatter(formatter)
logging.getLogger('').addHandler(console)

# 在具体代码中可以直接使用

logging.info(xxx)

logging.error(xxx)

对于非正常情况退出的记录:

try:
    check_appserver()
except Exception, e:
    exception_log = "./appserverchecklog/exception_%s.log"%time.strftime("%Y%m%d%H%M%S")
    f=open(exception_log,'a')
    f.write("[%s] got exceptions

"%time.strftime("%Y-%m-%d %H:%M:%S"))
    traceback.print_exc(file=f)
    f.flush()
    f.close()
    #TODO 缺一个发送提醒的功能

另外也可以直接用logging来写

try:

    xxxx

except Exception, e:

    logger.error('Failed to execute xxxx', exc_info = True)
