示例1: GetStats

// Get cgroup and networking stats of the specified container
func GetStats(cgroupManager cgroups.Manager, networkInterfaces []string) (*info.ContainerStats, error) {
	cgroupStats, err := cgroupManager.GetStats()
	if err != nil {
		return nil, err
	}
	libcontainerStats := &libcontainer.Stats{
		CgroupStats: cgroupStats,
	}
	stats := toContainerStats(libcontainerStats)

	// TODO(rjnagal): Use networking stats directly from libcontainer.
	stats.Network.Interfaces = make([]info.InterfaceStats, len(networkInterfaces))
	for i := range networkInterfaces {
		interfaceStats, err := sysinfo.GetNetworkStats(networkInterfaces[i])
		if err != nil {
			return stats, err
