CAdvisor 是谷歌开发的用于分析运行中容器的资源占用和性能指标的开源工具。
CAdvisor 是一个运行时的守护进程，负责收集、聚合、处理和输出运行中容器的信息。
基于 Prometheus 安装文章进行的试验。
安装测试
安装 docker
配置docker的yum源

安装docker-ce
yum install docker-ce -y
启动
systemctl start docker
启动 cAdvisor 容器
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=8090:8080 \ --detach=true \ --name=cadvisor \ google/cadvisor:latest
查看容器状态
[root@es01 ~]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 70f072038935 google/cadvisor:latest "/usr/bin/cadvisor -…" 3 days ago Up 3 days 0.0.0.0:8080->8080/tcp cadvisor

访问测试
通过 http://ip:port 进行访问:
prometheus 服务端配置
编辑 prometheus.yml 配置文件，在 scripe_configs 下添加下面内容:
- job_name: 'cadvisor'
metrics_path: '/metrics'
static_configs:
- targets: ['10.0.20.11:8080']
使用 promtool 检查配置文件
[root@es01 config]# /opt/prometheus-2.14/bin/promtool check config /opt/prometheus-2.14/config/prometheus.yml Checking /opt/prometheus-2.14/config/prometheus.yml SUCCESS: 0 rule files found
重新加载配置文件
curl -X POST http://10.0.20.11:9090/-/reload
