Logstash grok失败了

Question

我试图找到一条消息，但它在日志中没有_grokparsefailure，但实际上并没有说明它失败了。 grok查询适用于https://grokdebug.herokuapp.com/

input {
  file {
  type => "apache-access"
  path => "C:/prdLogs/sent/*"
}
   filter {
   grok {
  match => ['message', '%{IP:clientip} - - \[%{GREEDYDATA:raw_timestamp}   \] "%{WORD:httpmethod} %{NOTSPACE:referrer} HTTP/%{NUMBER:httpversion}" %{NUMBER:response} "-" "%{NOTSPACE:request}" %{QS:UserAgent} %{WORD:httpmethodO} - - HTTP/%{NUMBER:httpversion2} "%{WORD:session}:%{WORD:httpmed}" "-" %{NUMBER:duration}' ]
}
   date {
    match => [ "raw_timestamp" , 'dd/MMM/yyyy:HH:mm:ss Z' ]
    target => '@timestamp'
   }
  }

   output {
elasticsearch { hosts => ["111.44.44.44:9200"] }
  }

数据看起来像：

这实际上是一个apache访问日志，但我无法使用COMBINEDAPACHELOG或COMMONAPACHELOG。实际上是同样的错

elasticsearch中的所有条目都标记为“_grokparsefailure”。我在调试模式下使用log.level运行logstash但是在日志中没有看到任何错误。

我使用的是最新版本的logstash。

请指教。

R2 D2谢谢，我试过这个但没有快乐:(

我创建了一个模式文件并粘贴了你的模式。我刚刚将有效负载更改为“130.39.22.22 - [23 / Feb / 2015：10：18：45 +0800]”，以下是我的过滤器：

filter {

grok {
      patterns_dir => ["c:/logstashconfig/patterns"]
      match => ['message', '%{IP:clientip} - - /[%{DATE_CUSTOM:timestamp}/]'] 
    }
date {
    match => [ "timestamp" , 'dd/MMM/yyyy:HH:mm:ss Z' ]
    target => '@timestamp'
  }
}

logstash中的调试日志：

{
      "path" => "C:/prdLogs/sent/test",
"@timestamp" => 2017-03-03T00:06:15.269Z,
      "@version" => "1",
      "host" => "hkw20012125",
   "message" => "130.39.22.22 - -     [23/Feb/2015:10:18:45 +0800]\r",
      "type" => "apache-access",
      "tags" => [
    [0]     "_grokparsefailure"
]   
}

有任何想法吗？它是数据末尾的+0800吗？谢谢。

Answer 1

我想一旦你的模式中有GREEDYDATA，就意味着要从日志中考虑你的其余部分：

GREEDYDATA的模式如下：

GREEDYDATA .* <-- means to capture the entire line

如果我没有弄错的话，你的grok匹配看起来应该是这样的：

grok {
  match => ['message', '%{IPV4:clientip} - - %{GREEDYDATA:data}']
}

除非您需要单独提取值，否则上面的grok应该为您完成。我认为你匹配timestamp的方式是错误的。为了处理你的timestamp，你需要在你的模式文件中有以下模式：

MONTHDAY (?:(?:0[1-9])|(?:[12][0-9])|(?:3[01])|[1-9])
MONTH \b(?:Jan(?:uary)?|Feb(?:ruary)?|Mar(?:ch)?|Apr(?:il)?|May|Jun(?:e)?|Jul(?:y)?|Aug(?:ust)?|Sep(?:tember)?|Oct(?:ober)?|Nov(?:ember)?|Dec(?:ember)?)\b
YEAR (?>\d\d){1,2}
TIME (?!<[0-9])%{HOUR}:%{MINUTE}(?::%{SECOND})(?![0-9])
DATE_CUSTOM %{MONTHDAY}[/]%{MONTH }[/]%{YEAR}:%{TIME}

然后你可以在你的grok比赛中使用它：

grok {
    match => ['message', '%{IPV4:clientip} - - \[%{DATE_CUSTOM:timestamp} %{GREEDYDATA:data}']
}

现在你将能够匹配timestamp：

date {
    match => [ "timestamp" , 'dd/MMM/yyyy:HH:mm:ss Z' ]
    target => '@timestamp'
}

希望这可以帮助！

Answer 2

当你必须建立自己的模式时，从左侧开始，慢慢地，并使用debugger。

如果您测试此模式：

%{IP:clientip} - - \[

它有效，但这一个：

%{IP:clientip} - - \[%{GREEDYDATA:raw_timestamp}   \]

没有。将模式与输入进行比较表明时间戳和关闭括号之间没有空格。

将此部分模式更改为：

%{IP:clientip} - - \[%{GREEDYDATA:raw_timestamp}\]

作品。
