springboot 发送logback日志到elk_spring boot logback日志推送到vue

1.     引入依赖

<dependency>
   <groupId>net.logstash.logback</groupId>
   <artifactId>logstash-logback-encoder</artifactId>
   <version>4.11</version>
</dependency>

 

2.     日志配置

在logback.xml文件添加如下配置：

<appender name="LOGSTASH"
       class="net.logstash.logback.appender.LogstashTcpSocketAppender">
   <destination>xx.xx.xx.xx:5044</destination>
   <!-- encoder必须配置,有多种可选 -->
   <encoder charset="UTF-8"
          class="net.logstash.logback.encoder.LogstashEncoder" >
      <!-- "logName":"comba-community" 的作用是指定创建索引的名字时用，并且在生成的文档中会多了这个字段  -->
      <customFields>{"logName":"comba-community"}</customFields>
   </encoder>
   <filter class="ch.qos.logback.classic.filter.LevelFilter">
      <level>INFO</level>
   </filter>
</appender>

 

<!-- additivity 避免执行2次 -->
<logger name="com.comba.controller" level="INFO" additivity="false">
   <appender-ref ref="STDOUT" />
   <appender-ref ref="INFO_FILE" />
   <appender-ref ref="ERROR_FILE" />
   <appender-ref ref="DEBUG_FILE" />
   <appender-ref ref="LOGSTASH" />
</logger>
 
<root level="${root.level}">
   <appender-ref ref="STDOUT" />
   <appender-ref ref="INFO_FILE" />
   <appender-ref ref="ERROR_FILE" />
   <appender-ref ref="DEBUG_FILE" />
   <appender-ref ref="LOGSTASH" />
</root>

有多个logstash IP添加如下配置：

<connectionStrategy>
<roundRobin>
<connectionTTL>5minutes</connectionTTL>
</roundRobin>
</connectionStrategy>

这个配置是向logstash输出日志如果有多个logstash IP或端口可以轮询负载各端口

3.     Logstash配置

input {
    tcp {
        port => 5044
        mode => "server"
        tags => ["tags"]
        codec => json_lines
    }
}
 
output {
  elasticsearch {
    hosts => "192.168.2.210:9200"
    index => "%{[logName]}-%{+YYYY.MM.dd}"
    user => "elastic"
    password => "changeme"
  }

#控制台输出日志
  #stdout {codec => rubydebug }
}

服务器logstash控制输出的日志：
