如何使用logstash获取输出中的列值

Question

我正在使用csv文件和logstash。我能够在过滤器中获取列值，但我无法在输出中获得这些值。我正在使用的配置文件是：

input {
  file {
    path => "/Users/B0079855/Documents/SERVERS/logstash-2.2.2/samples/products.csv"
    # to read from the beginning of file
    start_position => beginning
    sincedb_path => "/dev/null"
  }
}

filter {
    csv {
        columns => ["COL1", "COL2"]
    }
}

output {
    stdout { codec => rubydebug }
}

是否也可以在输出中获取列值？

如果您拥有CSV过滤器，该怎么办？

filter{
    csv {
        fields => ["COL1", "COL2"]
        separator => ","   <---------add this  
    }
}
