Logstash-连接两个dict

我写了一个小的工作示例来解释我的问题：

input {
  stdin {
      codec => "json"
  }
}
filter {
    mutate {
        rename => { "[DictA]" => "[ZielDict]" } 
        rename => { "[DictB]" => "[ZielDict]" } 
    }
}
output {
  stdout {}
}

输入

输出

{
      "@version" => "1",
          "host" => "78f85c66a671",
    "@timestamp" => 2018-11-15T12:11:01.193Z,
      "ZielDict" => {
        "valueB" => 456
    }
}

想要输出（我不想覆盖DictA！）

如您所见，我希望附加到ZielDict，而不是用DictB覆盖它。我该怎么办？ 提前谢谢

使用以下选项：

通过此配置，您可以获得：

{
    "host" => "frsred-0077",
    "@timestamp" => 2018-11-15T13:54:19.923Z,
    "DictA" => {
        "valueB" => 456,
        "valueA" => 123
    },
    "DictB" => {
        "valueB" => 456
    },
    "@version" => "1"
}

您必须删除

DictB

字段并重命名

DictA

，以获得所需的输出

{
      "@version" => "1",
          "host" => "78f85c66a671",
    "@timestamp" => 2018-11-15T12:11:01.193Z,
      "ZielDict" => {
        "valueA" => 123
        "valueB" => 456
    }
}

input {
  stdin {
      codec => "json"
  }
}
filter {
    mutate {
        merge => { "DictA" => "DictB" } 
    }
}
output {
  stdout {}
}

{
    "host" => "frsred-0077",
    "@timestamp" => 2018-11-15T13:54:19.923Z,
    "DictA" => {
        "valueB" => 456,
        "valueA" => 123
    },
    "DictB" => {
        "valueB" => 456
    },
    "@version" => "1"
}
