导致 logstash 挂掉:

  此时这个表达式匹配不上:
          match => [
             "message" , "\s*%{IPORHOST:clientip}\s+\-\s+\-\s+\[%{HTTPDATE:time}\]\s+\"%{WORD:verb}\s+(?<api>(\S+))\?.*\s+HTTP/%{NUMBER:httpversion}\"\s+%{NUMBER:http_status_code}\s+%{NUMBER:bytes}\s+(%{BASE16FLOAT:request_time})\s+%{IPORHOST:remoteip}",
              "message" ,"\s*%{IPORHOST:clientip}\s+\-\s+\-\s+\[%{HTTPDATE:time}\]\s+\"%{WORD:verb}\s+(?<api>(\S+))\s+HTTP/%{NUMBER:httpversion}\"\s+%{NUMBER:http_status_code}\s+%{NUMBER:bytes}\s+(%{BASE16FLOAT:request_time})\s+%{IPORHOST:remoteip}",
             "message" ,"\s*%{IPORHOST:clientip}\s+\-\s+\-\s+\[%{HTTPDATE:time}\]\s+\"%{WORD:verb}\s+(?<api>(\S+))\s+HTTP/%{NUMBER:httpversion}\"\s+%{NUMBER:http_status_code}\s+\-\s+(%{BASE16FLOAT:request_time})\s+%{IPORHOST:remoteip}"

	需要补上一条:
\s*%{IPORHOST:clientip}\s+\-\s+\-\s+\[%{HTTPDATE:time}\]\s+\"%{WORD:verb}\s+(?<api>(\S+))\s+HTTP/%{NUMBER:httpversion}\"\s+%{NUMBER:http_status_code}\s+\-\s+(%{BASE16FLOAT:request_time})\s+(%{IPORHOST:remoteip}|-)

此时正常:
