logstash 配置管道

Question

我有一個看起來像這樣的日志文件

116.50.181.5 - - [18/May/2015:19:05:32 +0000] "GET /images/web/2009/banner.png HTTP/1.1" 200 52315 "http://www.semicomplete.com/style2.css" "Mozilla/5.0 (X11; Linux x86_64; rv:26.0) Gecko/20100101 Firefox/26.0"

我的logstash配置如下：

input {  
    file {
       path => "C:\Users\PC\Documents\elk\Input\listening.txt"
       start_position => "beginning"
      }
    }
filter {
  grok {
    match => {
      "message" => '%{IPORHOST:clientip} %{USER:ident} %{USER:auth} \[%{HTTPDATE:timestamp}\] "%{WORD:verb} %{DATA:request} HTTP/%{NUMBER:httpversion}" %{NUMBER:response:int} (?:-|%{NUMBER:bytes:int}) %{QS:referrer} %{QS:agent}'
    }
  }

  date {
    match => [ "timestamp", "dd/MMM/YYYY:HH:mm:ss Z" ]
    locale => en
  }

  geoip {
    source => "clientip"
  }

  useragent {
    source => "agent"
    target => "useragent"
  }
}

    output {
      elasticsearch 
      {
        hosts => "http://localhost:9200"
        index => "log"
      }  


    }

一切正常，我在 logstash 中沒有錯誤，但數據沒有按預期出現在 elasticsearch 中。

也許我的代碼有問題或缺失。

Answer 1

在您的輸入中添加以下代碼

start_position => "beginning"
sincedb_path => "/dev/null"

sincedb_path => "/dev/null"表示它不存儲sincedb文件。 這些文件保留了日志存儲在文件上的位置的字節偏移。

然后轉到 logstash/data/plugins/inputs/file 目錄。 之后在此目錄下運行以下命令

rm -r .sincedb*

最后運行您的 logstash 管道。 它應該工作。
