安装 Prometheus + Grafana

docker 编排

  prometheus:
    image: prom/prometheus:v2.40.1
    container_name: prometheus
    ports:
      - "9090:9090"
    volumes:
      - /docker/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml
    network_mode: "host"

  grafana:
    image: grafana/grafana:9.2.4
    container_name: grafana
    environment:
      TZ: Asia/Shanghai
      # 服务地址 用于指定外网ip或域名
      GF_SERVER_ROOT_URL: ""
      # admin 管理员密码
      GF_SECURITY_ADMIN_PASSWORD: 123456
    ports:
      - "3000:3000"
    volumes:
      - /docker/grafana/grafana.ini:/etc/grafana/grafana.ini
      - /docker/grafana:/var/lib/grafana
    network_mode: "host"

配置文件编写

prometheus.yml

# my global config
global:
  scrape_interval:     15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
  evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
  # scrape_timeout is set to the global default (10s).


# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
# 需要监控什么 在这里增加即可
scrape_configs:
  - job_name: 'Prometheus'
    static_configs:
      - targets: ['127.0.0.1:9090']
  - job_name: 'Grafana'
    static_configs:
      - targets: ['127.0.0.1:3000']

grafana.ini 官方默认配置 按需更改

内容过多 请查看下方附件

启动 Prometheus 与 Grafana

执行 docker 命令安装启动

docker-compose up -d prometheus grafana
1

查看 prometheus 控制台

访问 9090 端口进入控制台 找到上方菜单 Status -> Targets
查看我们配置好的数据源节点采集状态

查看 Grafana 控制台

访问 3000 端口输入配置好的账号密码 进入控制台

配置 prometheus 数据源采集

进入右侧菜单 Configuration -> Data Sources

点击右侧 Add data source

选择 prometheus 类型 填写 prometheus 地址与超时时间 然后点击下方保存

配置监控页面

进入 Grafana 官方 监控模板仓库 在这里可以找到各式各样的监控模板
https://grafana.com/grafana/dashboards/

搜索框输入 prometheus 往下翻找到 Prometheus 2.0 Overview 这个模板

点击右侧 copy ID 这里ID为 3662 然后回到 Grafana 控制台
点击右侧菜单 Dashboards -> Import

输入刚才复制的 模板ID 点击 Load 下载模板

选择我们配置好的 prometheus 数据源 点击下方导入 即可完成模板的配置导入
