}

func SwapMemory

func SwapMemory() (*SwapMemoryStat, error)

type VirtualMemoryStat

type VirtualMemoryStat struct {
	// Total amount of RAM on this system
	Total uint64 `json:"total"`

	// RAM available for programs to allocate
	//
	// This value is computed from the kernel specific values.
	Available uint64 `json:"available"`

	// RAM used by programs
	//
	// This value is computed from the kernel specific values.
	Used uint64 `json:"used"`

	// Percentage of RAM used by programs
	//
	// This value is computed from the kernel specific values.
	UsedPercent float64 `json:"usedPercent"`

	// This is the kernel's notion of free memory; RAM chips whose bits nobody
	// cares about the value of right now. For a human consumable number,
	// Available is what you really want.
	Free uint64 `json:"free"`

	// OS X / BSD specific numbers:
	// http://www.macyourself.com/2010/02/17/what-is-free-wired-active-and-inactive-system-memory-ram/
	Active   uint64 `json:"active"`
	Inactive uint64 `json:"inactive"`
	Wired    uint64 `json:"wired"`

	// Linux specific numbers

	// https://www.kernel.org/doc/Documentation/filesystems/proc.txt
	Buffers      uint64 `json:"buffers"`
	Cached       uint64 `json:"cached"`
	Writeback    uint64 `json:"writeback"`
	Dirty        uint64 `json:"dirty"`
	WritebackTmp uint64 `json:"writebacktmp"`
	Shared       uint64 `json:"shared"`

	PageTables   uint64 `json:"pagetables"`
	SwapCached   uint64 `json:"swapcached"`
}

Memory usage statistics. Total, Available and Used contain numbers of bytes for human consumption.

The other fields in this struct contain kernel specific values.
