Cgroup files with docker on mesos


I am running docker as a containerizer with Mesos. On this Mesos cluster, am trying to validate some container metrics/stats that I am able to see with docker remote API. However, am not able to locate the cgroups files for my docker containers. I don’t find them under, for example, /sys/fs/cgroup/cpuacct/docker/{CONTAINER_ID}. Could someone help me with this? Am I looking at the right place? Note that we launch docker containers from within our custom mesos-executor.

Thank you
