Functions

func CgroupCPU

func CgroupCPU(containerID string, base string) (*cpu.TimesStat, 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.TimesStat, error)

func GetDockerIDList

func GetDockerIDList() ([]string, error)

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

Types

type CgroupDockerStat

type CgroupDockerStat struct {
	ContainerID string `json:"containerID"`
	Name        string `json:"name"`
	Image       string `json:"image"`
	Status      string `json:"status"`
	Running     bool   `json:"running"`
}

func GetDockerStat

func GetDockerStat() ([]CgroupDockerStat, error)

GetDockerStat returns a list of Docker basic stats. This requires certain permission.
