CAdvisor

cAdvisor or container advisor is open source software that has native support for Docker containers, and is designed as a daemon that collects, aggregates, processes and exports information about running containers.

In this write-up, we won’t go into the details of how to compile or build cAdvisor; instead, we will focus on using a ready-to-run cAdvisor image from hub.docker.com and then run the image.

First, we need to set up the Docker environment and then enable it using systemctl. If you are on a distro that does not use systemd, then /etc/init.d/docker would be the most common command to start Docker.
