This library is based on the docker-stats library written by Peter Elger elger.peter@gmail.com (http://peterelger.com/) and Matteo Collina matteo.collina@nearform.com, but it draws the statistics direct from the filesystem, as opposed to using the stats endpoint in the Docker API. This allows it to be selective about what stats to include, which allows it to work comfortably with many, many running containers.
