logger.py

# -*- coding:utf-8 -*-
import sys

from slack_log_handler import SlackLogHandler

#
# logger の基本設定
#
logger = logging.getLogger()
logger.setLevel(logging.DEBUG)
formatter = logging.Formatter('%(asctime)s [%(levelname)s] %(message)s')

#
# 標準出力 Handler
#
stream = logging.StreamHandler()
stream.setLevel(logging.DEBUG)
stream.setFormatter(formatter)

#
# Slack Handler

        logging.INFO: ':grinning:',

# logger に Handler を追加
