S3输入插件中的正则表达式

Question

我需要使用Regex在S3输入中获取前缀，但文档中不支持Regex。

文件夹列表如下：

logs/20180304/app1/app1.log
logs/23180304/app2/app2.log
logs/20180305/app1/app1.log
logs/23180305/app2/app2.log
logs/20180306/app1/app1.log
logs/23180306/app2/app2.log

我在Logstash中的输入插件

  s3
       {
         access_key_id => "ABDCWERJKPOKJVB"
         secret_access_key => "4356ytghnfvgbh09oiujsedfvgh0piod"
         region => "as-sfg-2"
         bucket => "new-logs"
         prefix => "log/*/app1/app1.log
       }
 s3
       {
         access_key_id => "ABDCWERJKPOKJVB"
         secret_access_key => "4356ytghnfvgbh09oiujsedfvgh0piod"
         region => "as-sfg-2"
         bucket => "new-logs"
         prefix => "log/*/app1/app2.log
       }

我尝试了上面的前缀，但是logstash没有从这些前缀中获取日志
