springboot里连接elk里的logstash,然后写指定index索引的日志,而之后使用kibana去查询和分析日志,使用elasticsearch去保存日志。
添加引用
implementation 'net.logstash.logback:logstash-logback-encoder:5.3'
添加配置
<?xml version="1.0" encoding="UTF-8"?>
<configuration debug="false">
<!--定义日志文件的存储地址 勿在 LogBack 的配置中使用相对路径-->
<property name="LOG_HOME" value="./logs" />
<!-- 控制台输出 -->
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
<!--格式化输出:%d表示日期,%thread表示线程名,%-5level:级别从左显示5个字符宽度%msg:日志消息,%n是换行符-->
<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg %n</pattern>
</encoder>
</appender>
<appender name="logstash" class="net.logstash.logback.appender.LogstashTcpSocketAppender">
<param name="Encoding" value="UTF-8"/>
<destination>127.0.0.1:5000</destination>
<encoder charset="UTF-8" class="net.logstash.logback.encoder.LogstashEncoder" >
<customFields>{"appname":"elkDemo"}</customFields>
</encoder>
</appender>
<!-- 日志输出级别 -->
<root level="INFO">
<appender-ref ref="STDOUT" />
<appender-ref ref="logstash" />
</root>
</configuration>
指定配置
server.port=81
logging.config=classpath:logback-spring.xml
logstash配置索引
input {
tcp {
port => 5000
codec => "json"
}
}
## Add your filters / logstash plugins configuration here
output {
elasticsearch {
hosts => "elasticsearch:9200"
user => "elastic"
password => "changeme"
index => "%{[appname]}"
}
}
kibana里建立索引
通过kiban菜单去建立索引:Management>Index patterns>Create index pattern,这里会显示可用的索引名称。
