amazon-cloudwatchlogs - 如何在 Cloudwatch Log Insights 中按聚合对结果进行排序？

Question

我有一个非常简单的查询：

fields @timestamp, req.url, msg
| sort @timestamp desc
| filter msg = "request completed"
| stats count() by req.url

它显示了我的应用程序提供的所有请求，按 url 聚合。但是，我还想按聚合的值对结果进行排序count()- 但两者都| sort count desc不起作用| sort "count()" desc。我怎样才能做到这一点？

Answer 1

事实证明，我所要做的就是使用别名，然后按它排序：

fields @timestamp, msg, req.url
| filter msg="request completed"
| stats count() as count by req.url
| sort count desc
