logstash 2.2以上版本,nginx 错误日志切割

网上nginx错误日期切分的版本各式各样,能用的没几个,踩过很多坑,特意记录下:

if [type] == "xx_app_nginx_error_log" {
        grok    {
          patterns_dir => "/etc/logstash/conf.d/patterns"
          match => { "message" => "%{NGINXERROR_1}" }
        }
        mutate {
          #避免日期报错
          gsub => ["nginxErrorDateTime","/","-"]
          rename=>["host", "nginxErrorHost"]
        }
        #切最后一段错误信息
        if [nginxErrorInfo] {        #下面有些版本的logstash使用get会报错
            ruby{
              code => "
            new_event = LogStash::Event.new(Hash[event[‘nginxErrorInfo‘].split(‘, ‘).map{|l| l.split(‘: ‘)}])
            new_event.remove(‘@timestamp‘)
            event.append(new_event)"

            }
          }　　　　　　#下面这段是用了IPIP库,不用的话可以去掉
          ipip {
            source => "client"
            target =>  "ipip"
          }
          grok {
            patterns_dir => "/etc/logstash/conf.d/patterns"
            match => {"request"=>"%{NGINXERROR_REQUEST}"}

          }
          #删除以下字段,减少重复内容
          mutate{
            remove_field => [ "message","nginxErrorInfo","request"]
          }
          }

grok详细信息

NGINXERROR_1 (?<nginxErrorDateTime>\d{4}/\d{2}/\d{2}\s+\d{2}:\d{2}:\d{2})\s+\[(?<nginxErrorType>\w+)\]\s+\S+:\s+\*\d+(?<nginxErrorMsg>[^,]+), (?<nginxErrorInfo>.*)$
NGINXERROR_REQUEST "%{WORD:method} %{URIPATH:urlPath}(?:\?(?<urlParams>[^ ]+))? HTTP/%{NUMBER:httpVersion}"

输出:
