Metric histograms for tracking various durations.

Types

type HistogramMetric

type HistogramMetric interface {
	Observe(float64)
}

HistogramMetric represents an interface for counting individual observations.

type ScheduleMetrics

type ScheduleMetrics struct {
	// contains filtered or unexported fields
}

ScheduleMetrics holds the metrics and data related to scheduling and binding.

func NewScheduleMetrics

func NewScheduleMetrics(clock clock.Clock) *ScheduleMetrics

NewScheduleMetrics creates a new ScheduleMetrics instance.

func (*ScheduleMetrics) Done

func (m *ScheduleMetrics) Done(key string)

Done is called when a task is completed to record the duration.

func (*ScheduleMetrics) SinceInSeconds

func (m *ScheduleMetrics) SinceInSeconds(start time.Time) float64

SinceInSeconds returns the time duration in seconds since the provided start time.

func (*ScheduleMetrics) StartBind

func (m *ScheduleMetrics) StartBind(key string)

StartBind marks the start time of binding for a given key.

func (*ScheduleMetrics) StartSchedule

func (m *ScheduleMetrics) StartSchedule(key string)

StartSchedule marks the start time of scheduling for a given key.
