Setting up performance monitoring

We have tools such as SNMP, Nagios, and so on to monitor bare metal, VM performance. Similarly, there are a few tools/plugins available to monitor container performance such as cAdvisor (https://github.com/google/cadvisor) and Prometheus (https://prometheus.io). In this recipe, let's see how we can configure cAdvisor.

Getting ready

Perform the following to set up cAdvisor:

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

$ sudo docker container 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 \
    google/cadvisor:latest

• If you want to run cAdvisor outside Docker, then follow the instructions given on the cAdvisor home page: https://github.com/google/cadvisor/blob/master/docs/running.md#standalone.
