多次将python wsgi日志记录到远程服务器

Question

在apache / wsgi应用程序中，我试图将我的应用程序执行的操作记录到远程rsyslog守护程序。但是我不知道为什么，我要记录的日志在日志文件中多次记录。调用测试URL的时间，我有一个新的日志行，第二次有两个新行（在第一个之上），依此类推...我不知道为什么，也不清楚。是否知道什么可能导致此行为？

谢谢

import logging, socket, os, json, requests, sys
from logging.handlers import SysLogHandler

def application(environ, start_response):
        status = '200 OK'
        html_output = 'App test\n'
        logger = logging.getLogger('test app')
        logger.setLevel(logging.INFO)
        handler = logging.handlers.SysLogHandler('/dev/log')
        formatter = logging.Formatter('Python: { "loggerName":"%(name)s", "timestamp":"%(asctime)s", "pathName":"%(pathname)s", "logRecordCreationTime":"%(created)f", "functionName":"%(funcName)s", "levelNo":"%(levelno)s", "lineNo":"%(lineno)d", "time":"%(msecs)d", "levelName":"%(levelname)s", "message":"%(message)s"}')
        handler.formatter = formatter
        logger.addHandler(handler)
        logger.info('need to sync true')
        response_headers = [('Content-type', 'text/html'), ('Content-Length', str(len(html_output)))]
        start_response(status, response_headers)
        return [bytes(html_output,  'utf-8')]

在/ var / log / messages中有一些日志行，您可以多次看到同一行：
