Memory usage statistics. Total, Available and Used contain numbers of bytes for human consumption.
The other fields in this struct contain kernel specific values.
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:
