Boto3 CloudFront对象使用计数 [英] Boto3 CloudFront Object Usage Count

问题描述

希望统计CloudFront Dist中的所有对象分别被击中的次数，以便我可以生成Excel表来跟踪使用情况统计数据。我一直在浏览CloudFront的boto3文档，但我还不能确定在哪里可以访问到这些信息。我看到AWS CloudFront控制台会生成一个"热门对象"报告。我不确定是否有人知道如何获取AWS在boto3中为该报告生成的数字？

如果无法通过Boto3访问，是否有我应该改用的AWS CLI命令？

更新：

以下是我最终使用的伪代码，希望这是其他人的起点：

推荐答案

发件人Configuring and Using Standard Logs (Access Logs) - Amazon CloudFront：

您可以将CloudFront配置为创建包含有关CloudFront收到的每个用户请求的详细信息的日志文件。这些日志称为标准日志，也称为访问日志。这些标准日志可用于Web和RTMP分发。如果启用标准日志，您还可以指定希望CloudFront保存文件的Amazon S3存储桶。

日志文件可能非常大，但您可以Query Amazon CloudFront Logs using Amazon Athena。
