一.监控架构图

二.使用docker-compose启动skywalking以及ES

version: '3.3'
services:
  es8:
    image: elasticsearch:8.4.2
    container_name: es8
    ports:
      - 9200:9200
      - 9300:9300
    environment:
      xpack.security.enabled: "false"
      discovery.type: "single-node" #单例模式
      ingest.geoip.downloader.enabled: "false"
      #锁定物理内存地址，防止es内存被交换出去，也就是避免es使用swap交换分区，频繁的交换，会导致IOPS变高
      bootstrap.memory_lock: "true"
      ES_JAVA_OPTS: "-Xms6g -Xmx6g" #堆内存大小
      TZ: Asia/Shanghai
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - /home/data/skywalking/elasticsearch/data:/usr/share/elasticsearch/data
 
  skywalking-oap:
    image: apache/skywalking-oap-server:9.4.0
    container_name: skywalking-oap
    restart: always
    depends_on:
      - es8
    links:
      - es8
    ports:
      - 11800:11800
      - 12800:12800
    environment:
      SW_CORE_RECORD_DATA_TTL: 7 #记录数据的���效期，单位天
      SW_CORE_METRICS_DATA_TTL: 7 #分析指标数据的有效期，单位天
      SW_ENABLE_UPDATE_UI_TEMPLATE: "true" # 开启dashboard编辑修改功能
      SW_HEALTH_CHECKER: default
      TZ: Asia/Shanghai
      SW_STORAGE: elasticsearch
      JAVA_OPTS: "-Xms2048m -Xmx2048m"
      #SW_STORAGE: elasticsearch7
      SW_STORAGE_ES_CLUSTER_NODES: es8:9200
    #volumes:
      #- ./config:/skywalking/config
 
  skywalking-ui:
    image: apache/skywalking-ui:9.4.0
    #image: apache/skywalking-ui:9.0.0
    container_name: skywalking-ui
    restart: always
    depends_on:
      - skywalking-oap
    links:
      - skywalking-oap
    ports:
      - 18080:8080
    environment:
      TZ: Asia/Shanghai
      SW_HEALTH_CHECKER: default
      SW_OAP_ADDRESS: http://skywalking-oap:12800

三.部署java agent，运行

nohup /usr/local/jdk-11/bin/java -javaagent:/home/wwwroot/skywalking-agent/skywalking-agent.jar -Dskywalking.agent.service_name=java-test -Dskywalking.collector.backend_service=192.168.10.16:11800 -jar java-test.jar  --spring.config.local=application.yml &

注意事项：agent要加在应用包前面启动。

四.可以直接登录skywalking进行查看了。
