#grok & kv插件

官方提供的grok表达式
https://github.com/logstash-plugins/logstash-patterns-core/tree/master/patterns

grok在线调试
http://grokdebug.herokuapp.com/

配置文件示例：
ELK安装笔记

直接调用grok表达式: %{IPV4:client} (%{USERNAME:ident}|-) (%{USERNAME:auth}|-) \[%{HTTPDATE:timestamp}\]

ELK安装笔记

自定义正则：(?<client>\d{3}.\d{3}.\d{1}.\d{2})
