Functions

func GetCgroupPathTypeDocker

func GetCgroupPathTypeDocker(containerId string) (string, error)

func GetCgroupPathTypeSystem

func GetCgroupPathTypeSystem(containerId string) (string, error)

cgroupPath 指 subsystems 的相对路径，如/sys/fs/cgroup/cpu/ 目录下的相对路径 /test 在Ubuntu中，对于容器而言，相对路径即 /docker/{containerID<no-trunc>}
