如何通过组合输入csv的两个字段/列来在logstash中生成@timestamp

Question

我们在csv文件中有来自外部源的数据:

orderid,OrderDate,BusinessMinute,Quantity,Price
31874,01-01-2013,00:06,2,17.9

数据date在一列和time另一列中 - 我需要通过将这两列组合在一起来生成时间戳.

我正在使用csv filterlogstash中的以下配置从文件中读取上述数据 - 这是生成自己的时间戳:

input {  
  file {
      path => "/root/data/import/Order.csv"
      start_position => "beginning"
  }
}
filter {
    csv {
        columns => ["orderid","OrderDate","BusinessMinute","Quantity","Price"]
        separator => ","
    } 
}
output {  
    elasticsearch {
        action => "index"
        host => "localhost"
        index => "demo"
        workers => 1
    }
}

如何组合OrderDate + Business Minute作为@timestamp？

Answer 1

使用mutate过滤器将OrderDate和BusinessMinute字段组合到单个(临时)字段中,然后使用日期过滤器并在成功时删除该字段.

filter {
  mutate {
    add_field => {
      "timestamp" => "%{OrderDate} %{BusinessMinute}"
    }
  }
  date {
    match => ["timestamp", "..."]
    remove_field => ["timestamp"]
  }
}
