Springboot集成graylog快速入门demo

一、graylog介绍

GrayLog是一个轻量型的分布式日志管理平台，一个开源的日志聚合、分析、审计、展示和预警工具。在功能上来说，和ELK类似，但又比ELK要简单轻量许多。依靠着更加简洁，高效，部署使用简单的优势很快受到许多公司的青睐。 GrayLog包含Elasticsearch、MongoDb 和Graylog三个模块

二、graylog环境搭建

这里采用docker-compose来搭建graylog测试环境，具体配置如下

yaml 复制代码

# docker-compose配置参考：https://docs.graylog.org/en/3.3/pages/installation/docker.html
version: '3'

services:

  mongo:
    image: mongo:3
    container_name: graylog_demo_mongo
    restart: unless-stopped
    #    volumes:
    #      - ./graylog/mongo_data:/data/db
    networks:
      - graylog

  elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch-oss:6.8.10
    container_name: graylog_demo_elasticsearch
    restart: unless-stopped
    #    volumes:
    #      - ./graylog/es_data:/usr/share/elasticsearch/data
    environment:
      - http.host=0.0.0.0
      - transport.host=localhost
      - network.host=0.0.0.0
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    deploy:
      resources:
        limits:
          memory: 1g
    networks:
      - graylog

  graylog:
    image: graylog/graylog:3.3
    container_name: graylog_demo_graylog
    restart: unless-stopped
    #    volumes:
    #      - ./graylog/graylog_data_journal:/usr/share/graylog/data/journal
    environment:
      - GRAYLOG_PASSWORD_SECRET=somepasswordpepper # CHANGE ME (must be at least 16 characters)!
      - GRAYLOG_ROOT_PASSWORD_SHA2=8c6976e5b5410415bde908bd4dee15dfb167a9c873fc4bb8a81f6f2ab448a918 # Password: admin
      - GRAYLOG_HTTP_EXTERNAL_URI=http://127.0.0.1:9000/ # TODO 这里填写自己的ip地址
    ports:
      # Graylog web interface and REST API
      - 9000:9000
      # Syslog TCP
      - 1514:1514
      # Syslog UDP
      - 1514:1514/udp
      # GELF TCP
      - 12201:12201
      # GELF UDP
      - 12201:12201/udp
    networks:
      - graylog
    depends_on:
      - mongo
      - elasticsearch

# 网桥graylog -> 方便相互通讯
networks:
  graylog:
    driver: bridge

启动服务

css 复制代码

docker-compose -f docker-compose-graylog.yml -p graylog_demo up -d

访问地址：http://ip地址:9001 默认登录账号密码：admin/admin

2.1、新建input http input

测试是否正常发送

makefile 复制代码

curl -XPOST http://localhost:12201/gelf -p0 -d '{"message":"hello这是一条消息", "host":"127.0.0.1", "facility":"test", "topic": "meme"}'

2.2、创建 gref udp input

由于http发送效率比较低，所以后面springboot会采用UDP方法来采集日志

三、代码工程
