Types ¶
type Event ¶
type Event interface {
// String returns the string representation of this event, preferably as the
// name used by "perf record -e".
String() string
// SetAttrs sets the attributes for this event in the [unix.PerfEventAttr]
// struct.
SetAttrs(*unix.PerfEventAttr) error
}
An Event represents a performance event that perf can count.
func ParseEvent ¶
type EventScale ¶
type EventScale interface {
Event
// ScaleUnit returns the factor to multiply raw values by to compute a
// meaningful value, plus the unit of that value. A no-op implementation
// should return 1.0, "".
ScaleUnit() (scale float64, unit string)
}
An EventScale is an Event that provides a scaling factor and unit to convert raw values into meaningful values.
