aws中國區(qū)目前并沒有提供批量添加告警的功能，需要通過cli編寫程序的方式來實(shí)現(xiàn)圆恤。

說明：

1.需要部署aws cli并配置權(quán)限突倍。
2.此腳本基于python3環(huán)境

import json
import subprocess

# 1. 配置cli路徑和region
Contants = {
    "AWSCLI": '"aws" --output json',
    "AWSREGION": ['cn-north-1']  # 北京
}


# 構(gòu)造字典
class CreateDict(dict):
    def __getitem__(self, item):
        try:

        except KeyError:
            value = self[item] = type(self)()
            return value
