Question

我正在尝试使用logstash将csv导入elasticsearch 我尝试过两种方式：

使用CSV
使用grok过滤器

1）对于下面的csv是我的logstash文件：

input {
  file {
    path => "path_to_my_csv.csv"
    start_position => "beginning"
    sincedb_path => "/dev/null"
  }
}
filter {
  csv {
        separator => ","
        columns => ["col1","col2_datetime"]
  }
  mutate {convert => [ "col1", "float" ]}
  date {
        locale => "en"
        match => ["col2_datetime", "ISO8601"] // tried this one also - match => ["col2_datetime", "yyyy-MM-dd HH:mm:ss"]
        timezone => "Asia/Kolkata"
        target => "@timestamp" // tried this one also - target => "col2_datetime"
   }
}
output {
   elasticsearch {
     hosts => "http://localhost:9200"
     index => "my_collection"

  }
  stdout {}
}

2）使用grok过滤器：

对于下面的grok过滤器是我的logstash文件

input {
  file {
    path => "path_to_my_csv.csv"
    start_position => "beginning"
    sincedb_path => "/dev/null"
  }
}
filter {
  grok {
    match => { "message" => "(?<col1>(?:%{BASE10NUM})),(%{TIMESTAMP_ISO8601:col2_datetime})"}
    remove_field => [ "message" ]
  }
  date {
        match => ["col2_datetime", "yyyy-MM-dd HH:mm:ss"]
   }
}
output {
   elasticsearch {
     hosts => "http://localhost:9200"
     index => "my_collection_grok"

  }
  stdout {}
}

问题：

因此，当我单独运行这两个文件时，我能够在elasticsearch中导入数据。但我的日期字段没有解析为datetime类型，而是保存为字符串，因此我无法运行日期过滤器。

有人可以帮我弄清楚它为什么会发生。我的弹性搜索版本是5.4.1。

Answer 1

我对配置文件进行了2次更改。

1）删除列名col2_datetime

中的under_score

2）添加目标

以下是我的配置文件的样子......

vi logstash.conf

input {
  file {
    path => "/config-dir/path_to_my_csv.csv"
    start_position => "beginning"
    sincedb_path => "/dev/null"
  }
}
filter {
  csv {
        separator => ","
        columns => ["col1","col2"]
  }
  mutate {convert => [ "col1", "float" ]}
  date {
        locale => "en"
        match => ["col2",  "yyyy-MM-dd HH:mm:ss"]
        target => "col2"
   }
}
output {
   elasticsearch {
     hosts => "http://172.17.0.1:9200"
     index => "my_collection"

  }
  stdout {}
}

这是数据文件：

vi path_to_my_csv.csv

1234365,2016-12-02 19:00:52 
1234368,2016-12-02 15:02:02 
1234369,2016-12-02 15:02:07

elasticsearch - 使用logstash日期导入csv不会解析为datetime类型
