有道理, 当初考虑过用 name, 但是会碰到一个问题是所有的表达式都需要用 join, 会比较复杂. 当时考虑的是通常都是从警报或者 overview 看板跳转到这个单实例看板上的, 这些跳转之间用 ID 会更合理. 不知道有没有什么更好的建议?

嗯，可以修改一下 但要注意 aliyun_rds_* 指标中并没有 description tag，因此用这个变量查询 aliyun_rds_* 指标的时候，需要通过 join 把 description 转成 id

抱歉这么晚才注意到 问题在于响应体的 json 中没有 Datapoints 字段, 推断是阿里云那边因为限流或其他原因返回了非正常的返回体😅 下一个版本会修复这个问题, 正确打印出阿里云返回异常结果的原因

For anyone who encountered the same issue: This is a bad error handling for bad responses from the Cloud Monitor API, and this will be addressed in next release hopefully.
