如何在 logstash 中拆分文件名？

Question

我正在从 s3 存储桶中注入一个文件到 logstash，我的文件名包含一些信息，我想将文件名拆分为多个字段，以便将它们用作单独的字段。请帮助我，我是麋鹿的新手。

input {
 s3 {
    bucket => "***********"
    access_key_id => "***********"
    secret_access_key => "*******"
    "region" => "*********"
    
    "prefix" => "Logs"
    "interval" => "1"
    "additional_settings" => {
           "force_path_style" => true
           "follow_redirects" => false
           }
    }
}

filter {
  mutate {
    add_field => {
      "file" => "%{[@metadata][s3][key]}"              //This file name have to split
    }
   
  }
}

output {
 elasticsearch {
  hosts => ["localhost:9200"]
  index => "indexforlogstash"
     
 }
}

Answer 1

在 filter 部分，您可以利用 dissect filter 来实现您想要的：

filter {
    ...

    dissect {
      mapping => {
        "file" => "Logs/%{deviceId}-%{buildId}-log.txt"
      }
    }
}

通过此过滤器后，您的文档将获得两个新字段，即：

• deviceId (1232131)
• buildId (custombuildv12)
