我已经在elasticsearch中创建了一个索引来存储一些测试日志，但是我无法从logstash中获取要加载的数据。我在ES中创建了索引：

put sonicwall
    {
      "mappings":{
        "properties":{
          "Time": { "type":"text"},
          "Category": { "type":"text"},
          "Group": { "type":"text"},
          "Event":{ "type":"text"},
          "Priority":{ "type":"text"}
        }
      }
    }

创建索引

现在，我的logstash配置文件：

input{
        file{
            path => "C:/Elastic/logsPrueba/log3.csv"
            start_position => beginning
        }
    }
    filter{
        csv{
            separator => ","
            columns => ["Time","Category","Group","Event","Priority"]
        }
        
    }
    output{
        
        elasticsearch{
            hosts => ["localhost:9200"]
            index => "sonicwall"
        }
        stdout {}
    }

这就是CSV

当我运行logstash时，数据永远不会加载

有人能帮帮我吗
