<pre name="code" class="html"><pre name="code" class="html"> 多项选择有时候我们会碰上一个日志有多种可能格式的情况。这时候要写成单一正则就比较困难，或者全用 | 隔开又比较丑陋。这时候，logstash 的语法提供给我们一个有趣的解决方式。文档中，都说明 logstash/filters/grok 插件的 match 参数应该接受的是一个 Hash 值。但是因为早期的 logstash 语法中 Hash 值也是用 [] 这种方式书写的，所以其实现在传递 Array 值给 match 参数也完全没问题。所以，我们这里其实可以传递多个正则来匹配同一个字段：match => [    "message", "(?<request_time>\d+(?:\.\d+)?)",    "message", "%{SYSLOGBASE} %{DATA:message}",    "message", "(?m)%{WORD}"]logstash 会按照这个定义次序依次尝试匹配，到匹配成功为止。虽说效果跟用 | 分割写个大大的正则是一样的，但是可阅读性好了很多。 [elk@dr-mysql01 api-access]$ cat /usr/local/logstash-2.3.4/config/api-access/logstash_access.conf input {        file {                type => "zj_api_access"                path => ["/data01/applog_backup/zjzc_log/zj-api*access*"]        }           file {                 type => "wj_api_access"                 path => ["/data01/applog_backup/winfae_log/wj-api*access*"]         }  }filter {    grok {        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}",             "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}|-)"        ]    }           mutate {                        convert => [ "request_time", "float"]                       add_field =>["response_time","%{request_time}"]                        remove_field =>["request_time"]                       add_field => [ "[@metadata][zabbix_key]" , "logstash-api-access" ]                       add_field => [ "[@metadata][zabbix_host]" , "dr-mysql01" ]                        add_field =>["messager","%{type}-%{message}"]                         remove_field =>["message"]                }   date {        match => ["time", "dd/MMM/yyyy:HH:mm:ss Z"]    }     }output {     if [response_time] >= 5  {          zabbix {zabbix_host => "[@metadata][zabbix_host]"zabbix_key => "[@metadata][zabbix_key]"        zabbix_server_host => "192.168.32.55"        zabbix_server_port => "10051"zabbix_value => "messager"        }          }     if [type] == "zj_api_access" {         redis {                host => "192.168.32.67"                data_type => "list"                key => "zj_api_access:redis"                port=>"6379"                password => "1234567"        }}      else if [type] == "wj_api_access"{       redis {                 host => "192.168.32.67"                 data_type => "list"                 key => "wj_api_access:redis"                 port=>"6379"                 password => "1234567"         } }}
