使用docker compose在多个节点上执行Prometheus + Grafana，

Question

我正在使用cadvisor和node_exporter设置prometheus + grafana。我需要收集2台以上服务器的指标。但可以说我要2个不做。我正在使用docker compose。

在主服务器上，我有以下配置：

[root@172.31.115.207 ~]# cat prometheus.yml 
scrape_configs:
  - job_name: prometheus
    scrape_interval: 5s
    static_configs:
    - targets:
      - prometheus:9090
      - pushgateway:9091
  - job_name: docker
    scrape_interval: 5s
    static_configs:
    - targets:
      - 172.31.115.207:9323
  - job_name: cadvisor
    scrape_interval: 5s
    static_configs:
    - targets: ['172.31.112.84:8080','172.31.115.207:8080']
  - job_name: node-exporter
    scrape_interval: 5s
    static_configs:
    - targets: ['172.31.112.84:9100','172.31.115.207:9100']

cat prometheus.yml
      - 172.31.115.207:9323
  - job_name: cadvisor
    scrape_interval: 5s
    static_configs:
    - targets: ['172.31.112.84:8080','172.31.115.207:8080']
  - job_name: node-exporter
    scrape_interval: 5s
    static_configs:
    - targets: ['172.31.112.84:9100','172.31.115.207:9100'] 
[root@pivanko1c ~]# cat docker-compose.yml
version: '3'
services:
  prometheus:
    image: prom/prometheus:latest
    container_name: prometheus
    ports:
      - 9090:9090
    command:
      - --config.file=/etc/prometheus/prometheus.yml
    volumes:
      - ./prometheus.yml:/etc/prometheus/prometheus.yml:ro
    depends_on:
      - cadvisor
  cadvisor:
    image: google/cadvisor:latest
    container_name: cadvisor
    ports:
      - 8080:8080
    volumes:
      - /:/rootfs:ro
      - /var/run:/var/run:rw
      - /sys:/sys:ro
      - /var/lib/docker/:/var/lib/docker:ro
  pushgateway:
    image: prom/pushgateway
    container_name: pushgateway
    ports:
      - 9091:9091
  node-exporter:
    image: prom/node-exporter:latest
    container_name: node-exporter
    restart: unless-stopped
    ports:
      - 9100:9100
  grafana:
    image: grafana/grafana
    container_name: grafana
    ports:
      - 3000:3000
    environment:
      - GF_SECURITY_ADMIN_PASSWORD=Uniform189
    depends_on:
      - prometheus
      - cadvisor

这是我的docker-compose.yml;在工作服务器上

[root@172.31.112.84 ~]# cat docker-compose.yml 
version: '3'
services:
  cadvisor:
    image: google/cadvisor:latest
    container_name: cadvisor
    ports:
      - 8080:8080
    volumes:
      - /:/rootfs:ro
      - /var/run:/var/run:rw
      - /sys:/sys:ro
      - /var/lib/docker/:/var/lib/docker:ro
  node-exporter:
    image: prom/node-exporter:latest
    container_name: node-exporter
    restart: unless-stopped
    ports:
      - 9100:9100

当我仅设置了主人后，在grafana中一切看起来都很好。但是，当我在工作节点上启动容器时，grafana会出错。我只看到容器的数量。其他所有内容均为N / A。

请您告知我的配置问题出在哪里？我想在grafana中有个不错的视图，在这里可以选择node1或node2并查看所有指标。

谢谢
