SpringCloud整合ELK实现日志收集
ELK中各个服务的作用
- ElasticSearch:用于存储收集到的日志
- Logstash:用于收集日志，SpringCloud整合Logstash后会把日志发送到Logstash， Logstash再把日志转发给ElasticSearch
- Kibana：可视化界面查看日志
搭建ELK
创建配置文件
input {
tcp {
mode => "server"
host => "0.0.0.0"
port => 4560
codec => json_lines
}
}
output {
elasticsearch {
hosts => "es:9200"
index => "springcloud-appname-%{+YYYY.MM.dd}"
}
}
Docker-compose搭建ELK环境

启动ELK
docker-compose up -d
进入logstash容器并安装json_lines插件
# 进入logstash容器
docker exec -it logstash bash
#安装插件
/bin/logstash-plugin install logstash-codec-json_lines
# 退出容器
exit
# 重启容器
docker restart logstash
SpringCloud项目集成Logstash
pom.xml文件中添加logstash-logback-encoder依赖
<dependency>
<groupId>net.logstash.logback</groupId>
<artifactId>logstash-logback-encoder</artifactId>
</dependency>
编写xml配置文件让logback的日志输出到logstash
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration>
<configuration>
<include resource="org/springframework/boot/logging/logback/defaults.xml"/>
<include resource="org/springframework/boot/logging/logback/console-appender.xml"/>
<!--应用名称-->
<property name="APP_NAME" value="your-app-name"/>
<!--日志文件保存路径-->
<property name="LOG_FILE_PATH" value="${LOG_FILE:-${LOG_PATH:-${LOG_TEMP:-${java.io.tmpdir:-/tmp}}}/logs}"/>
<contextName>${APP_NAME}</contextName>
<!--每天记录日志到文件appender-->
<appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<fileNamePattern>${LOG_FILE_PATH}/${APP_NAME}-%d{yyyy-MM-dd}.log</fileNamePattern>
<maxHistory>30</maxHistory>
</rollingPolicy>
<encoder>
<pattern>${FILE_LOG_PATTERN}</pattern>
</encoder>
</appender>
<!--输出到logstash的appender-->
<appender name="LOGSTASH" class="net.logstash.logback.appender.LogstashTcpSocketAppender">
<!--可以访问的logstash日志收集端口-->
<destination>your-ip:4560</destination>
<encoder charset="UTF-8" class="net.logstash.logback.encoder.LogstashEncoder"/>
</appender>
<root level="INFO">
<appender-ref ref="CONSOLE"/>
<appender-ref ref="FILE"/>
<appender-ref ref="LOGSTASH"/>
</root>
</configuration>
