How should I use TaggingHandler？

[zxfzqf]

OS:window 10 python version：3.6

I want different levels of logging to be saved to different files. I use TaggingHandler, but it not work, I was wrong？What do I need to do?

import os
import time
import datetime
import logbook
from multiprocessing import Pool
from logbook import Logger, FileHandler
from logbook.more import TaggingHandler

handler_tag = TaggingHandler(dict(
    info=logbook.StderrHandler(level=logbook.INFO, format_string='{record.time:%Y-%m-%d %H:%M:%S}|{record.level_name}|{record.message}'),
    warning=logbook.FileHandler('two_file_log.log', mode='a')
))

handler_tag.push_application()
logger = Logger()

def process_log(p_off):

    for _ in range(0, 100):
        d = datetime.datetime.now()
        t_str = 'testtest' * 2000
        logger.info('{}:{}:p_off({}):pid({})'.format(t_str, d.strftime('%Y-%m-%d %H:%M:%S'), p_off, os.getpid()))

if __name__ == '__main__':

    logger.info('start.....')
    p = Pool(8)
    for i in range(4):
        p.apply_async(process_log, args=(i,))
    print('waiting.....')
    p.close()
    p.join()
    print('done.....')

I try use MultiProcessingHandler ,but it lost data, Is it wrong for me to use the method?

import os
import time
import datetime
import logbook
from multiprocessing import Pool
from multiprocessing import Queue
from logbook import Logger, FileHandler, TimedRotatingFileHandler
from logbook.queues import MultiProcessingHandler, MultiProcessingSubscriber

queue = Queue(-1)
handler_tag = MultiProcessingHandler(queue)
handler_tag.push_application()
logger = Logger()

target_handlers = logbook.NestedSetup([
    logbook.NullHandler(),
    logbook.FileHandler('file_log.log', mode='a', level=logbook.DEBUG)
])

sub = MultiProcessingSubscriber(queue)
c = sub.dispatch_in_background(target_handlers)

def process_log(p_off):
    for x in range(0, 100):
        d = datetime.datetime.now()
        t_str = 'testtest%d'%x
        logger.warning('{}:{}:p_off({}):pid({})'.format(t_str, d.strftime('%Y-%m-%d %H:%M:%S'), p_off, os.getpid()))

if __name__ == '__main__':

    logger.info('start.....')
    p = Pool(4)
    for i in range(4):
        p.apply_async(process_log, args=(i,))
    print('waiting.....')
    p.close()
    p.join()
    print('done.....')
