整体架构

部署

博主使用的是docker compose进行部署, 编辑完成docker-compose.yaml文件后启动即可

docker compose 启动后台服务命令
docker compose up -d

示例 docker-compose.yaml 文件

version: '3.4'
services:
  prometheus:
    image: prom/prometheus
    container_name: prometheus
    #设置容器中的hostname，同个网络之中的容器可以通过hostname找到对应容器
    hostname: prometheus
    ports:
      - 9090:9090
    volumes:
      # prometheus 配置文件
      - /XX/prometheus.yml:/etc/prometheus/prometheus.yml
      # 同步容器和宿主机时间戳
      - /etc/localtime:/etc/localtime:ro
  prometheus-exporter:
    # 网上有很多已经构建的exporter供下载使用，这里使用容器化exporter，如果需要宿主机的数据可以通过挂载或者物理部署的方式
    image: prom/node-exporter
    container_name: node-exporter
    hostname: node-exporter
    ports:
      - 9100:9100
    volumes:
      - /etc/localtime:/etc/localtime:ro
  grafana:
    image: grafana/grafana
    container_name: grafana
    hostname: grafana
    ports:
      - 3010:3000
    volumes:
      - /etc/localtime:/etc/localtime:ro
      - /XX/grafana.ini:/etc/grafana/grafana.ini

grafana.ini 配置文件参考 Grafana Github

示例 prometheus 配置文件

# 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).

# Alertmanager configuration 配置监控报警
alerting:
  alertmanagers:
    - static_configs:
        - targets:
          # - alertmanager:9093

# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
  # - "first_rules.yml"
  # - "second_rules.yml"

# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.

# 这里是主要配置数据源的地方，即获取各种exporter的数据进行定时采集整理
scrape_configs:
  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  - job_name: "prometheus"
    # metrics_path defaults to '/metrics'，配置数据获取路由
    # scheme defaults to 'http'，请求协议配置
    static_configs:
      - targets: ["prometheus:9090"] #配置请求地址和端口
  
  # 配置抓取的数据
  - job_name: "node_test"
    static_configs:
      - targets: ["prometheus-exporter:9100"]

  # 每个target会作为grafana中的host或者instance显示
