• ELK学习笔记(四)SpringBoot+Logback+Redis+ELK实例


    废话不多说,直接上干货,首先看下整体应用的大致结构。(整个过程我用到了两台虚拟机  应用和Shipper 部署在192.168.25.128 上 Redis和ELK 部署在192.168.25.129上)

    Controller:

    @RestController
    @RequestMapping("/user")
    public class UserController {
    
        private Logger logger = LoggerFactory.getLogger(UserController.class);
    
        @RequestMapping(value = "/addUser", method = RequestMethod.GET)
        public Object addUser() {
            String[] names = {"Jack", "Tom", "John", "Arnold", "Jim", "James", "Rock"};
            String[] introduce = {"I like to collect rock albums", "I like to build cabinets",
                    "I like playing computer games", "I like climbing mountains", "I love running",
                    "I love eating", "I love drinking"};
            for (int i = 0; i < 1000; i++) {
                Random random = new Random();
                int tempNum = random.nextInt(7);
                User user = new User();
                user.setId(i);
                user.setAge(random.nextInt(20) + 20);
                user.setIntroduce(introduce[tempNum]);
                user.setName(names[tempNum] + i);
                logger.info(JSON.toJSONString(user));
            }
            return new ResponseData(200, "Success");
        }
    
    }

    通过nohup方式启动我们的SpringBoot应用

    nohup java -jar -Dserver.port=8080 -Dlog.root=/var/log/springboot-elk/  /opt/springboot-elk/springboot-elk.jar >/dev/null 2>&1 &

    LogStash shipper配置:

    input {
      file {
         path => "/var/log/springboot-elk/*"
         type => "springboot-elk"
      }
    }
    
    output {
    
      redis {
            data_type => "list"
            key => "springboot-elk-list"
            host => "192.168.25.129"
            port => 6379
      }
    }

    保证指定的Redis实例开启后,运行LogStash:

    bin/logstash -f config/logback-logstash-redis.conf

    接下来我们访问应用来生成日志。

     

    生成成功,观察我们的Redis,数据已经全部进入了队列中。

     

    接下来我们配置LogStash 读取Redis数据放入ES中:

    input {
        redis {
            data_type => "list"
            key => "springboot-elk-list"
            host => "192.168.25.129"
            port => 6379
        }
    }
    
    output {
       elasticsearch {
         hosts => ["192.168.25.129:9200","192.168.25.129:9201"]  #从 1.5.0开始,host 可以设置数组,它会从节点列表中选取不同的节点发送数据,达到 Round-Robin负载均衡的效果。单节点也可以写成数组形式。
         index => "springboot-elk"
         user => elastic    #没装x-pack这边就不需要user和password了
         password => changeme
       }
    }

    运行LogStash后,它会自动从Redis指定的队列中读取数据放入ES。

    bin/logstash -f config/redis-logstash-es.conf

    启动Kibana,建立索引,观察数据是否进入了ES:

     可以看到1000条数据已经进入了ES  (^o^)/~ 。
