Monitoring Docker with cAdvisor

In this tutorial we will install cAdvisor and use it for monitoring Docker container.

What is cAdvisor? 

cAdvisor (Container Advisor) is a monitoring tool which is built and open sourced by Google for monitoring resource usage and performance characteristics of running containers. cAdvisor runs a daemon that collects, aggregates, processes, and exports information about running containers.

Install and Run cAdvisor

Pull latest google/cadvisor image from Docker Hub:

sudo su

docker pull google/cadvisor

Run cAdvisor container:

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

cAdvisor container runs on port 8080. You can access it on http://localhost:8080.
