Logstash无法读取简单文件

Question

我正在学习logstash而且我正在尝试读取文件并尝试将输出放入文件中。日志文件格式为

LogName      : System
LogName      : System

这是conf文件 -

input{
file {
    path => "<mypath>\wineventlog.txt"
    type => 'eventlog'
}
}
filter{
    if "eventlog" in [type] {
        grok {
            match => { 'message' => 'LogName\W+(?<LogName>[A-Za-z]{0,})'
                     }
            }
     }  
}
output{

  file{
        path => "<mypath>\output.txt"
  }

}

但是当我运行输出文件时

{"path":"<mypath>\\wineventlog.txt","@timestamp":"2017-04-11T16:17:40.732Z","@version":"1","host":"INFARSZB11617","message":"\u0000L\u0000o\u0000g\u0000N\u0000a\u0000m\u0000e\u0000 \u0000 \u0000 \u0000 \u0000 \u0000 \u0000:\u0000 \u0000S\u0000y\u0000s\u0000t\u0000e\u0000m\u0000\r\u0000","type":"eventlog","tags":["_grokparsefailure"]}
{"path":"<mypath>\\wineventlog.txt","@timestamp":"2017-04-11T16:17:40.748Z","@version":"1","host":"INFARSZB11617","message":"\u0000\r\u0000","type":"eventlog","tags":["_grokparsefailure"]}

请指导我在这做什么。仅供参考，我试图删除conf文件中的过滤器，然后我没有得到任何输出文件。
