var MemTotal func() (uint64, error)

MemTotal returns the total amount of RAM on this system

var MemUsed func() (uint64, error)

MemUsed returns the total used amount of RAM on this system

Functions

func ForceReadMemStats

func ForceReadMemStats() *runtime.MemStats

ForceReadMemStats is to force read memory stats.

func GetMemTotalIgnoreErr

func GetMemTotalIgnoreErr() uint64

GetMemTotalIgnoreErr returns the total amount of RAM on this system/container. If error occurs, return 0.

func InstanceMemUsed

func InstanceMemUsed() (uint64, error)

InstanceMemUsed returns the memory usage of this process

func MemTotalCGroup

func MemTotalCGroup() (uint64, error)

MemTotalCGroup returns the total amount of RAM on this system in container environment.

func MemTotalNormal

func MemTotalNormal() (uint64, error)

MemTotalNormal returns the total amount of RAM on this system in non-container environment.

func MemUsedCGroup

func MemUsedCGroup() (uint64, error)

MemUsedCGroup returns the total used amount of RAM on this system in container environment.

func MemUsedNormal

func MemUsedNormal() (uint64, error)

MemUsedNormal returns the total used amount of RAM on this system in non-container environment.

func ReadMemStats

func ReadMemStats() (memStats *runtime.MemStats)

ReadMemStats read the mem stats from runtime.ReadMemStats
