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".

The incudeMetrics arguments specifies which metrics are requested, and is used to filter out some cgroups and their mounts. If nil, all supported cgroup subsystems are included.

For cgroup v2, includedMetrics argument is unused, the only map key is "" (empty string), and the value is the unified cgroup mount point.

func NewCgroupManager

func NewCgroupManager(name string, paths map[string]string) (cgroups.Manager, error)
