用于uwsgi日志的Logstash Grok过滤器

Question

我是ELK堆栈的新用户.我正在使用UWSGI作为我的服务器.我需要使用Grok解析我的uwsgi日志,然后分析它们.

这是我的日志格式: -

[pid: 7731|app: 0|req: 357299/357299] ClientIP () {26 vars in 511 bytes} [Sun Mar  1 07:47:32 2015] GET /?file_name=123&start=0&end=30&device_id=abcd&verif_id=xyzsghg => generated 28 bytes in 1 msecs (HTTP/1.0 200) 2 headers in 79 bytes (1 switches on core 0)

我使用此链接生成我的过滤器,但它没有解析大部分信息.

上面链接生成的过滤器是

%{SYSLOG5424SD} %{IP} () {26 vars in 511 bytes} %{SYSLOG5424SD} GET %{URIPATHPARAM} => generated 28 bytes in 1 msecs (HTTP%{URIPATHPARAM} 200) 2 headers in 79 bytes (1 switches on core 0)

这是我的logstash-conf文件.

input { stdin { } }

filter {
  grok {
    match => { "message" => "%{SYSLOG5424SD} %{IP} () {26 vars in 511 bytes} %{SYSLOG5424SD} GET %{URIPATHPARAM} => generated 28 bytes in 1 msecs (HTTP%{URIPATHPARAM} 200) 2 headers in 79 bytes (1 switches on core 0)" }
  }
  date {
    match => [ "timestamp" , "dd/MMM/yyyy:HH:mm:ss Z" ]
  }
}

output {
  stdout { codec => rubydebug }
}

使用此conf文件运行logstash后,我收到一条错误消息: -

{
       "message" => "[pid: 7731|app: 0|req: 357299/357299] ClientIP () {26 vars in 511 bytes} [Sun Mar  1 07:47:32 2015] GET /?file_name=123&start=0&end=30&device_id=abcd&verif_id=xyzsghg => generated 28 bytes in 1 msecs (HTTP/1.0 200) 2 headers in 79 bytes (1 switches on core 0)",
      "@version" => "1",
    "@timestamp" => "2015-03-01T07:57:02.291Z",
          "host" => "cube26-Inspiron-3542",
          "tags" => [
        [0] "_grokparsefailure"
    ]
}

日期已正确格式化.我如何提取我的日志等信息,比如我query parameters(filename, start,end, deviceid etc)和ClientIP,Response code等等.

另外,是否有可以使用的内置UWSGI日志解析器,例如为apache和syslog构建的解析器？

我自己写了这个,但它抛出了同样的错误:

%{SYSLOG5424SD} %{IP:client_ip} () {%{NUMBER:vars} vars in %{NUMBER:bytes} bytes} %{SYSLOGTIMESTAMP:date} %{WORD:method} %{URIPATHPARAM:request} => generated %{NUMBER:generated_bytes} bytes in {NUMBER:secs} msecs (HTTP/1.0 %{NUMBER:response_code}) %{NUMBER:headers} headers in %{NUMBER:header_bytes} (1 switches on core 0)

我终于能够自己破解了.上述日志的GROK过滤器将是:

\[pid: %{NUMBER:pid}\|app: %{NUMBER:app}\|req: %{NUMBER:req_num1}/%{NUMBER:req_num2}\] %{IP:client_ip} \(\) \{%{NUMBER:vars} vars in %{NUMBER:bytes} bytes\} %{SYSLOG5424SD} %{WORD:method} /\?file_name\=%{NUMBER:file_name}\&start\=%{NUMBER:start}\&end\=%{NUMBER:end} \=\> generated %{NUMBER:generated_bytes} bytes in %{NUMBER:secs} msecs \(HTTP/1.0 %{NUMBER:response_code}\) %{NUMBER:headers} headers in %{NUMBER:header_bytes}

但我的问题仍然存在:

1. 在grop中是否有任何默认的uwsgi日志过滤器？**

2. 我一直在为不同的查询参数应用不同的匹配.grok中有什么东西可以自己获取不同的查询参数吗？

我找到了解压缩查询参数的方法: -

这是我的最终配置: -

对于日志行

[pid: 7731|app: 0|req: 426435/426435] clientIP () {28 vars in 594 bytes} [Mon Mar  2 06:43:08 2015] GET /?file_name=wqvqwv&start=0&end=30&device_id=asdvqw&verif_id=qwevqwr&lang=English&country=in => generated 11018 bytes in 25 msecs (HTTP/1.0 200) 2 headers in 82 bytes (1 switches on core 0)

配置是

input { stdin { } }

filter {
  grok {
    match => { "message" => "\[pid: %{NUMBER}\|app: %{NUMBER}\|req: %{NUMBER}/%{NUMBER}\] %{IP} \(\) \{%{NUMBER} vars in %{NUMBER} bytes\} %{SYSLOG5424SD:DATE} %{WORD} %{URIPATHPARAM} \=\> generated %{NUMBER} bytes in %{NUMBER} msecs \(HTTP/1.0 %{NUMBER}\) %{NUMBER} headers in %{NUMBER}" }
  }
  date {
    match => [ "timestamp" , "dd/MMM/yyyy:HH:mm:ss Z" ]
  }
  kv {
    field_split => "&? "
    include_keys => [ "file_name", "device_id", "lang", "country"]
  }
}


output {
  stdout { codec => rubydebug }
  elasticsearch { host => localhost }
}

我发现你的解决方案不支持HTTP/1.1.我修复它并添加变量名称.参考

这是我的grok配置:

grok {
  match => { "message" => "\[pid: %{NUMBER:pid}\|app: %{NUMBER:id}\|req: %{NUMBER:currentReq}/%{NUMBER:totalReq}\] %{IP:remoteAddr} \(%{WORD:remoteUser}?\) \{%{NUMBER:CGIVar} vars in %{NUMBER:CGISize} bytes\} %{SYSLOG5424SD:timestamp} %{WORD:method} %{URIPATHPARAM:uri} \=\> generated %{NUMBER:resSize} bytes in %{NUMBER:resTime} msecs \(HTTP/%{NUMBER:httpVer} %{NUMBER:status}\) %{NUMBER:headers} headers in %{NUMBER:headersSize} bytes %{GREEDYDATA:coreInfo}" }
}
date {
  match => [ "timestamp" , "dd/MMM/yyyy:HH:mm:ss Z" ]
}
