DevOps: Puppet, Docker, and Kubernetes

Setting up performance monitoring

We have tools such as SNMP, Nagios, and so on to monitor bare metal and VM performance. Similarly, there are a few tools/plugins available to monitor container performance such as cAdvisor (https://github.com/google/cadvisor) and sFlow (http://blog.sflow.com/2014/06/docker-performance-monitoring.html). In this recipe, let's see how we can configure cAdvisor.

Getting ready

Setting up cAdvisor.

• The easiest way to run cAdvisor is to run its Docker container, which can be done with the following command:

  sudo docker run \ 
    --volume=/:/rootfs:ro \ 
    --volume=/var/run:/var/run:rw \ 
    --volume=/sys:/sys:ro \ 
    --volume=/var/lib/docker/:/var/lib/docker:ro \ 
    --publish=8080:8080 \ 
    --detach=true \ 
    --name=cadvisor \
