Types

type RAMInfo

type RAMInfo struct {
	Total int64
	// Free is the amount of memory that is not being used.
	// This does not take into account memory that is being used for caching.
	// For more information, see the comments at the top of this file.
	Free      int64
	Used      int64
	Shared    int64
	Buffers   int64
	Cached    int64
	SwapTotal int64
	SwapFree  int64
	// contains filtered or unexported fields
}

RAMInfo is a struct that contains information about the running system's memory. Please see important notes in the struct definition.

type SystemInfo

type SystemInfo struct {
	// Uptime is the time since the system was booted.
	Uptime time.Duration
	// Loads is a 3 element array containing the 1, 5, and 15 minute load averages.
	Loads [3]uint64
	// RAM is a struct containing information about the system's RAM. See notes on this.
	RAM RAMInfo
	// Procs is the number of current processes.
	Procs uint16
}

func Sysinfo

func Sysinfo() (systemInfo *SystemInfo, err error)
