Cloud watch Log insights查询，结合两个querires

Question

我目前使用两种不同的 cloud watch log insights 查询，一种用于获取总请求数，另一种用于获取总错误数。以下是查询：

总人数：

fields @timestamp, @message
| filter @message like /reply.*MyAPI/
|parse @message '"reqID":*' as reqID
| stats count_distinct(reqID) as request_count by bin(1h) as hour

** 错误计数**

fields @timestamp, @message
| filter @message like /reply.*MyAPI.*Exception/
|parse @message '"reqID":*' as reqID
| stats count_distinct(reqID) as request_count by bin(1h) as hour

但是我想计算每个 bin 中的总请求数和错误请求数，并在可能的情况下通过单个查询计算每个 bin 的错误率（

error count

/

total request count

）。我该怎么做？
