推荐模板

Docker 容器监控：cAdvisor

VERSION=v0.36.0 # use the latest release version from https://github.com/google/cadvisor/releases
sudo docker run \
  --volume=/:/rootfs:ro \
  --volume=/var/run:/var/run:ro \
  --volume=/sys:/sys:ro \
  --volume=/var/lib/docker/:/var/lib/docker:ro \
  --volume=/dev/disk/:/dev/disk:ro \
  --publish=8080:8080 \
  --detach=true \
  --name=cadvisor \
  --privileged \
  --device=/dev/kmsg \
  gcr.io/cadvisor/cadvisor:$VERSION

*NIX 系统监控：Node Exporter

docker run -d \
  --net="host" \
  --pid="host" \
  -v "/:/host:ro,rslave" \
  quay.io/prometheus/node-exporter \
  --path.rootfs=/host
node-exporter:
    image: quay.io/prometheus/node-exporter
    restart: always
    network_mode: "host"
    pid: "host"
    ports:
      - '9100:9100'
    command:
      - --path.rootfs=/host
    volumes:
      - "/:/host:ro,rslave"

网络探测：Blackbox Exporter

docker run --rm -d -p 9115:9115 --name blackbox_exporter -v `pwd`:/config prom/blackbox-exporter:master --config.file=/config/blackbox.yml

Nginx 监控：Nginx Prometheus Exporter

# nginx.conf
location = /metrics {
  stub_status;
}
docker run -p 9113:9113 nginx/nginx-prometheus-exporter:0.8.0 -nginx.scrape-uri http://<nginx>:8080/stub_status
