logstash - 解析 Logstash 中的嵌套 JSON 字符串

Question

我正在以 json 格式登录logstash，我的日志有以下字段，每个字段都是一个字符串，atts字段是一个字符串化的json(注意:atts子字段每次都不同)

这是一个例子:

{"name":"bob","last":"builder", "atts":"{\"a\":111,\"b\":222}"}

我想将其解析为这样的内容:

   {
     "name" => "bob",
     "last" => "builder"
     "atss" => {
          "a" => 111,
          "b" => 222}
   }

这是我的配置:

input { stdin { } }  

filter {
  json {
    source => "message"
    target => "parsed"
  }
}
 output { stdout { codec => rubydebug  }}

好的，所以现在我明白了:

{
    "@timestamp" => 2017-04-05T12:19:04.090Z,
    "parsed" => {
        "atss" => "{\"a\":111, \"b\":222}",
        "name" => "bob",
        "last" => "the builder"
    },
        "@version" => "1",
          "host" => "0.0.0.0"
}

如何将 atts 字段解析为 json，以便我收到:

{
    "@timestamp" => 2017-04-05T12:19:04.090Z,
    "parsed" => {
        "atss" => 
           {"a" => 111,
            "b" => 222},
        "name" => "bob",
        "last" => "the builder"
    },
        "@version" => "1",
          "host" => "0.0.0.0"
}

感谢@Alcanzar，这就是我所做的

input { 
  stdin { } 
}  

filter {
  json {
    source => "message"
    target => "message"
  }
  json {
    source => "[message][atts]"
    target => "[message][atts]"
  }

}
 output { stdout { codec => rubydebug  }}
