Functions

func GetCgroupSubsystems

func GetCgroupSubsystems(includedMetrics container.MetricSet) (map[string]string, error)

GetCgroupSubsystems returns information about the cgroup subsystems that are of interest as a map of cgroup controllers to their mount points. For example, "cpu" -> "/sys/fs/cgroup/cpu".
