我想在 CloudWatch 上创建一个指标过滤器和一个基于它的警报,以通知我有关 S3 事件的信息,特别是当文件或存储桶设置为公共时。这是我用来创建指标的指标过滤器:
{ ($.eventSource = s3.amazonaws.com) && (($.eventName = PutBucketAcl) || ($.eventName = PutObjectAcl)) && (($.requestParameters.AccessControlPolicy.AccessControlList.Grant.Grantee.type = Group) )}
我pattern
通过输入以下内容对此进行了测试Custom log data

我单击了测试模式并收到此消息:
结果在示例日志中的 50 个事件中找到 0 个匹配项。
是metric filter
正确的吗?我应该有一个结果,但它没有出现。
