1, after completion of the installation Docker monitoring terminal, container Enabler cAdvisor

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 \
  google/cadvisor:latest

2, modify Promethus monitoring client configuration file: vim prometheus.yml

scrape_configs:
   # add operation, custom name 
  - job_name: ' Docker ' 
    # static add 
    static_configs:
     # designated monitor Example 
    - Targets: [ ' 47.98.138.176:8080 ' ]

3. Check and reload the configuration file

./promtool check config prometheus.yml
kill -hup PID

4, access to data is captured cAdvisor monitoring client: http: //47.98.138.176: 8080 / metrics

5, Prometheus monitoring client to see if intervention
