Types

type SI

type SI struct {
	Uptime       time.Duration // time since boot
	Loads        [3]float64    // 1, 5, and 15 minute load averages, see e.g. UPTIME(1)
	Procs        uint64        // number of current processes
	TotalRam     uint64        // total usable main memory size [kB]
	FreeRam      uint64        // available memory size [kB]
	SharedRam    uint64        // amount of shared memory [kB]
	BufferRam    uint64        // memory used by buffers [kB]
	TotalSwap    uint64        // total swap space size [kB]
	FreeSwap     uint64        // swap space still available [kB]
	TotalHighRam uint64        // total high memory size [kB]
	FreeHighRam  uint64        // available high memory size [kB]
	// contains filtered or unexported fields

func Get

func Get() *SI

Get the linux sysinfo data structure.

Example

si := Get()
fmt.Printf("%v\n", si.Loads)
fmt.Println(si.ToString())

func (SI) String

func (si SI) String() string

Make the "fmt" Stringer interface happy.

func (*SI) ToString

func (si *SI) ToString() string

Convert to string in a thread safe way.

 Output:
	uptime		279h6m21s
	load		0.12 0.04 0.05
	procs		143
	ram  total	383752 kB
	ram  free	254980 kB
	ram  buffer	7640 kB
	swap total	887800 kB
	swap free	879356 kB
