Spring Boot集成syslog快速入门

syslog简介

Syslog-ng是有Balabit IT Security Ltd.维护的额一套开源的Unix和类Unix系统的日志服务套件，它是一个灵活的、可伸缩的系统日志记录程序。对于服务器日志几种搜集，使用它是一个不错的解决方案。syslog-ng(syslog-Next Generation)是syslog的升级版

syslog-ng主要特性：

• 支持SSL/TSL协议

• 支持将日志写入数据库种，支持的数据库有Mysql、Microsoft SQL、Oracle、PostgreSql、SQLLite

• 支持标准的syslog协议

• 支持filter、parse和rewrite

• 支持更多的平台

• 更高的负载能力

环境准备

docker-compose.yml

version: '3.6'

services:
  syslog:
    image: lscr.io/linuxserver/syslog-ng:latest
    container_name: syslog-ng

    ports:
      - 514:5514/udp
      - 601:6601/tcp
      - 6514:6514/tcp
    volumes:
      - ./data/config:/config
      - ./data/log:/var/log #optional
    restart: unless-stopped

执行RUN命令

docker-compose -f docker-compose.yml up -d

down

docker-compose -f docker-compose.yml down

代码工程

将springboot应用日志发送到syslog-ng

1. 引入依赖

   <dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-web</artifactId>
       <exclusions>
           <exclusion>
               <groupId>org.springframework.boot</groupId>
               <artifactId>spring-boot-starter-logging</artifactId>
           </exclusion>
       </exclusions>
   </dependency>
   
   <dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-autoconfigure</artifactId>
   </dependency>
   <dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-test</artifactId>
       <scope>test</scope>
   </dependency>
   <dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-log4j2</artifactId>
   </dependency>

2. 编写测试代码

   import org.slf4j.Logger;
   import org.slf4j.LoggerFactory;
   import org.springframework.web.bind.annotation.RequestMapping;
   import org.springframework.web.bind.annotation.RequestParam;
   import org.springframework.web.bind.annotation.RestController;
   
   import java.util.HashMap;
   import java.util.Map;
   
   @RestController
   public class HelloWorldController {
       private final Logger logger = LoggerFactory.getLogger(HelloWorldController.class);
   
       @RequestMapping("/hello")
       public Map<String, Object> showHelloWorld(@RequestParam("n") String name){
           logger.info("Say hello to {}", name);
           Map<String, Object> map = new HashMap<>();
           map.put("msg", "HelloWorld");
           return map;
       }
   }

3. log配置

   <?xml version="1.0" encoding="UTF-8"?>
   <Configuration>
       <Appenders>
           <Console name="ConsoleAppender" target="SYSTEM_OUT">
               <PatternLayout
                       pattern="%style{%date{DEFAULT}}{yellow} %highlight{%-5level}{FATAL=bg_red, ERROR=red, WARN=yellow, INFO=green} %message%n"/>
           </Console>
           <Syslog name="Syslog" format="RFC5424" host="localhost" port="514"
                   protocol="UDP" appName="liuhaihua.cn" facility="LOCAL0" />
       </Appenders>
   
       <Loggers>
           <Root level="info">
               <AppenderRef ref="ConsoleAppender"/>
               <AppenderRef ref="Syslog"/>
   
           </Root>
       </Loggers>
   </Configuration>
