Exclude metric collection of certain cgroup groupnames

[chicofranchico]

On a certain machine I have different cgroup group names e.g.:

/sys/fs/cgroup/memory
/sys/fs/cgroup/memory/user
/sys/fs/cgroup/memory/mesos
/sys/fs/cgroup/memory/docker

Is there a way to collect only the docker group? I would like to avoid the collection of mesos for example.

Thanks in advance.

We recently added a "prefix whitelist": #1926, but don't expose it through flags, and just use /. We could add a flag to set this in cAdvisor.
Alternatively, we could allow setting the handlers that are enabled. I.E. collecting only from certain runtimes.
