analyze resource usage and performance of running containers

 cAdvisor (Container Advisor) provides container users an understanding of
 the resource usage and performance characteristics of their running
 containers.
 .
 cAdvisor has native support for Docker containers and should support just
 about any other container type out of the box.
 .
 cAdvisor also exposes container stats as Prometheus (http://prometheus.io)
 metrics.
 .
 This package provides golang library sources.
