logstash 安装插件multiline

Posted 2020-12-04 centos2017

在使用elk 传输记录 java 日志时，如下

一个java的报错

 

在elk中会按每一行 产生多条记录，不方便查阅

这里修改配置文件 使用  multiline   插件 即可实现多行合一的 输出模式

修改配置文件

# vi  /etc/logstash/conf.d/logstash.conf  

input {
 file {
    path => "/w_logs/error.log.2018-06-05"
    type => "test"
 }
}

filter {
   multiline {
            pattern => "^d{4}-d{1,2}-d{1,2}sd{1,2}:d{1,2}:d{1,2}"
            negate => true
            what => "previous"
        }

   grok {
       match => [ "message", "%{NOTSPACE:day} %{NOTSPACE:datetime}  %{NOTSPACE:level} %{GREEDYDATA:msginfo} " ]
   }
}


output {
 if [type] == "test" {
        elasticsearch {
            hosts => ["10.10.15.95:9200"]
            index => "12.83-test"
        }
  }
}

 

修改完 重启logstash
报错：
