+--raw_cgroup_prefix_whitelist: A comma-separated list of cgroup path prefix that needs to be collected even when -docker_only is specified
+--disable_root_cgroup_stats=false: Disable collecting root Cgroup stats.

 ## Container Hints
 
 Container hints are a way to pass extra information about a container to cAdvisor. In this way cAdvisor can augment the stats it gathers. For more information on the container hints format see its [definition](../container/common/container_hints.go). Note that container hints are only used by the raw container driver today.
