Functions

func ContainerOsVersion

func ContainerOsVersion() string

func GetClockSpeed

func GetClockSpeed(procInfo []byte) (uint64, error)

GetClockSpeed returns the CPU clock speed, given a []byte formatted as the /proc/cpuinfo file.

func GetHugePagesInfo

func GetHugePagesInfo(hugepagesDirectory string) ([]info.HugePagesInfo, error)

GetHugePagesInfo returns information about pre-allocated huge pages hugepagesDirectory should be top directory of hugepages Such as: /sys/kernel/mm/hugepages/

func GetMachineMemoryCapacity

func GetMachineMemoryCapacity() (uint64, error)

GetMachineMemoryCapacity returns the machine's total memory from /proc/meminfo. Returns the total memory capacity as an uint64 (number of bytes).
