LogStash.conf具有多个输出：数据显示在控制台上，但未发送到ElasticSearch服务器

Question

这是我的logstash.conf：

input {
    http {
        host => "127.0.0.1"
        port => 31311 
    }
}

output {
  elasticsearch {
    hosts => ["http://localhost:9200"]
  }
  stdout {
    codec => "rubydebug"
  }
}

作为测试，我在PowerShell中运行了以下命令：

  

C：\ Users \ Me \ Downloads \ curl-7.64.1-win64-mingw \ bin>。\ curl.exe -XPUT   “ http://127.0.0.1:31311/customer?pretty”

在我的Logstash控制台上，按预期，我看到了以下输出：

{
    "@timestamp" => 2019-04-08T13:45:40.267Z,
       "headers" => {
              "http_host" => "127.0.0.1:31311",
        "http_user_agent" => "curl/7.64.1",
           "request_path" => "/customer?pretty",
         "content_length" => "0",
         "request_method" => "PUT",
           "http_version" => "HTTP/1.1",
            "http_accept" => "*/*"
    },
          "host" => "127.0.0.1",
      "@version" => "1",
       "message" => ""
}

然后我运行以下命令：

  

C：\ Users \ Me \ Downloads \ curl-7.64.1-win64-mingw \ bin>。\ curl.exe -XGET   “ http://127.0.0.1:9200/_cat/indices?v”

我希望看到customer索引也是在我的ES服务器上创建的；但是，我所看到的只是

health status index uuid pri rep docs.count docs.deleted store.size pri.store.size

有一组空结果。

我想念什么？
