此程序用于Clickhouse和Hive数据的监控，Clickhouse数据的监控通过jdbc方式实现，Hive数据的监控通过调用subprocess模块，执行shell命令实现，当发现数据不符合设定条件时，会向企业微信群发送告警信息。

代码中需要配置文件conf.ini格式如下：

[dingding]
token=8a2a1327-ac40-44df-9097-d7527916868c

另外，程序中的"629b85***************"替换为自己的企业微信webhook中的key。

程序执行方式，假设命名上述监控程序为warn.py：

#监控hive仓库数据
python3 warn.py hive
#监控Clickhouse仓库数据
python3 warn.py clickhouse
