elasticsearch - 使用logstash日期導入csv不會解析為datetime類型

Question

我試圖使用logstash將csv導入elasticsearch我嘗試過兩種方法：

1. 使用CSV
2. 使用grok過濾器

1） 對於下面的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過濾器：

對於grok過濾器，下面是我的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 {}
}

問題：

因此，當我單獨運行這兩個文件時，我能夠在elasticsearch中導入數據。 但我的日期字段沒有解析為datetime類型，而是保存為字符串，因此我無法運行日期過濾器。

所以有人可以幫我弄清楚它為什么會發生。 我的彈性搜索版本是5.4.1。

提前致謝

Answer 1

我對配置文件進行了2次更改。

1）刪除列名col2_datetime中的under_score

2）添加目標

這是我的配置文件的樣子......

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 {}
}

這是數據文件：

vi path_to_my_csv.csv
