Functions

func CgroupCPU

func CgroupCPU(containerId string, base string) (*cpu.CPUTimesStat, error)

CgroupCPU returnes specified cgroup id CPU status. containerId is same as docker id if you use docker. If you use container via systemd.slice, you could use containerId = docker-<container id>.scope and base=/sys/fs/cgroup/cpuacct/system.slice/

func CgroupCPUDocker

func CgroupCPUDocker(containerid string) (*cpu.CPUTimesStat, error)

func GetDockerIDList

func GetDockerIDList() ([]string, error)

GetDockerIDList returnes a list of DockerID. This requires certain permission.
