logstash没有从日志文件中获取数据

Question

logstash配置有elasticsearch，其中应存储来自logstash的数据。配置已正确完成，仍然无法获取。

    input {
     file {
        path => "C:\Users\vishadub\Documents\elkstackTools\logs\error_log.log"
        type => "error_logs"
        start_position => beginning
        sincedb_path => "C:\Users\vishadub\Documents\elkstackTools\sincedb-access"
        }
     }

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

    this is written in my config file..
    o/p is below====
