Types

type GopsutilReader

type GopsutilReader struct{}

GopsutilReader implements Reader using gopsutil and tmux.

func NewGopsutilReader

func NewGopsutilReader() *GopsutilReader

NewGopsutilReader creates a new GopsutilReader.

func (*GopsutilReader) SessionRSSMB

func (g *GopsutilReader) SessionRSSMB(tmuxSessionName string) (int64, error)

SessionRSSMB returns the summed RSS in MB for all processes in a tmux session.

func (*GopsutilReader) SystemMemoryPct

func (g *GopsutilReader) SystemMemoryPct() (float64, error)

SystemMemoryPct returns used memory percentage via gopsutil.

type Reader

type Reader interface {
	// SystemMemoryPct returns the percentage of system RAM in use (0–100).
	// Returns 0 on platforms where measurement is unavailable.
	SystemMemoryPct() (float64, error)
	// SessionRSSMB returns the total RSS (resident set size) in MB for all
	// processes belonging to the given tmux session name.
	// Returns 0 if the session is not running or measurement fails.
	SessionRSSMB(tmuxSessionName string) (int64, error)
}
