前面的文章介绍了使用Node Exporter使用的方式。这篇文章继续介绍一下使用cadvisor提供容器监控指标，使用Prometheus进行收集，然后在Grafana中进行显示的方法。

事前准备

环境准备

Prometheus + cadvisor
用于准备如下版本的Prometheus和cadvisor服务

软件	版本信息
Prometheus	2.15.1
cadvisor	0.33.0

docker-compose配置文件信息如下所示：

liumiaocn:cadvisor liumiao$ cat docker-compose.yml 
version: '2'

services:
    prometheus:
        image: prom/prometheus:v2.15.1
        privileged: true
        volumes:
            - ./prometheus.yml:/etc/prometheus/prometheus.yml
        command:
            - '--config.file=/etc/prometheus/prometheus.yml'
        ports:
            - '9090:9090'

    cadvisor:
        image: google/cadvisor:v0.33.0
        container_name: cadvisor
        restart: unless-stopped
        ports:
          - '8080:8080'
        volumes:
          - /:/rootfs:ro
          - /var/run:/var/run:rw
          - /sys:/sys:ro
          - /var/lib/docker/:/var/lib/docker:ro
liumiaocn:cadvisor liumiao$

而Prometheus所用到的配置文件信息如下所示, 使用时需要将IP替换为本机的IP

liumiaocn:cadvisor liumiao$ cat prometheus.yml 
global:
  scrape_interval:     10s
  evaluation_interval: 10s

scrape_configs:
  - job_name: 'cadvisor'

    static_configs:
      - targets: ['192.168.31.242:8080']
        labels:
          group: 'cadvisor_group'
liumiaocn:cadvisor liumiao$

启动服务

liumiaocn:cadvisor liumiao$ docker-compose up -d
Creating network "cadvisor_default" with the default driver
Creating cadvisor              ... done
Creating cadvisor_prometheus_1 ... done
liumiaocn:cadvisor liumiao$ docker-compose ps
