Types

type CapturedCounter 

type CapturedCounter struct {
	CapturedMetricMeta
	// contains filtered or unexported fields
}

CapturedCounter atomically implements Counter and provides an atomic getter.

func (*CapturedCounter) Inc 

func (c *CapturedCounter) Inc(d int64)

Inc implements Counter.Inc.

func (*CapturedCounter) Value 

func (c *CapturedCounter) Value() int64

Value atomically returns the current value.

type CapturedGauge 

type CapturedGauge struct {
	CapturedMetricMeta
	// contains filtered or unexported fields
}

CapturedGauge atomically implements Gauge and provides an atomic getter.

func (*CapturedGauge) Update 

func (c *CapturedGauge) Update(d float64)

Update implements Gauge.Update.

func (*CapturedGauge) Value 

func (c *CapturedGauge) Value() float64

Value atomically returns the current value.

type CapturedMetricMeta 

type CapturedMetricMeta struct {
	Name string
	Tags map[string]string
}

CapturedMetricMeta is common information for captured metrics. These fields should never by mutated.

type CapturedTimer 

type CapturedTimer struct {
	CapturedMetricMeta
	// contains filtered or unexported fields
}

CapturedTimer atomically implements Timer and provides an atomic getter.

func (*CapturedTimer) Record 

func (c *CapturedTimer) Record(d time.Duration)

Record implements Timer.Record.

func (*CapturedTimer) Value 

func (c *CapturedTimer) Value() time.Duration

Value atomically returns the current value.

type CapturingHandler 

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

CapturingHandler is a Handler that retains counted values locally.

func NewCapturingHandler 

func NewCapturingHandler() *CapturingHandler

NewCapturingHandler creates a new CapturingHandler.

func (*CapturingHandler) Clear 

func (c *CapturingHandler) Clear()

Clear removes all known metrics from the root handler.

func (*CapturingHandler) Counter 

func (c *CapturingHandler) Counter(name string) Counter

Counter implements Handler.Counter.

func (*CapturingHandler) Counters 

func (c *CapturingHandler) Counters() []*CapturedCounter

Counters returns shallow copy of the local counters. New counters will not get added here, but the value within the counter may still change.

func (*CapturingHandler) Gauge 

func (c *CapturingHandler) Gauge(name string) Gauge

Gauge implements Handler.Gauge.

func (*CapturingHandler) Gauges 

func (c *CapturingHandler) Gauges() []*CapturedGauge

Gauges returns shallow copy of the local gauges. New gauges will not get added here, but the value within the gauge may still change.

func (*CapturingHandler) Timer 

func (c *CapturingHandler) Timer(name string) Timer

Timer implements Handler.Timer.

func (*CapturingHandler) Timers 

func (c *CapturingHandler) Timers() []*CapturedTimer

Timers returns shallow copy of the local timers. New timers will not get added here, but the value within the timer may still change.

func (*CapturingHandler) WithTags 

func (c *CapturingHandler) WithTags(tags map[string]string) Handler

WithTags implements Handler.WithTags.

type Counter 

type Counter interface {
	// Inc increments the counter value.
	Inc(int64)
}

Counter is an ever-increasing counter.

type CounterFunc 

type CounterFunc func(int64)

CounterFunc implements Counter with a single function.

func (CounterFunc) Inc 

func (c CounterFunc) Inc(d int64)

Inc implements Counter.Inc.

type Gauge 

type Gauge interface {
	// Update updates the gauge value.
	Update(float64)
}

Gauge can be set to any float.

type GaugeFunc 

type GaugeFunc func(float64)

GaugeFunc implements Gauge with a single function.

func (GaugeFunc) Update 

func (g GaugeFunc) Update(d float64)

Update implements Gauge.Update.

type Handler 

type Handler interface {
	// WithTags returns a new handler with the given tags set for each metric
	// created from it.
	WithTags(map[string]string) Handler

	// Counter obtains a counter for the given name.
	Counter(name string) Counter

	// Gauge obtains a gauge for the given name.
	Gauge(name string) Gauge

	// Timer obtains a timer for the given name.
	Timer(name string) Timer
}

Handler is a handler for metrics emitted by the SDK. This interface is intentionally limited to only what the SDK needs to emit metrics and is not built to be a general purpose metrics abstraction for all uses.

A common implementation is at go.temporal.io/sdk/contrib/tally.NewMetricsHandler. The NopHandler is a noop handler. A handler may implement "Unwrap() Handler" if it wraps a handler. 

var NopHandler Handler = nopHandler{}

NopHandler is a noop handler that does nothing with the metrics.

func NewReplayAwareHandler 

func NewReplayAwareHandler(replay *bool, underlying Handler) Handler

NewReplayAwareHandler is a handler that will not record any metrics if the boolean pointed to by "replay" is true.

type HandlerContextKey 

type HandlerContextKey struct{}

HandlerContextKey is the context key for a MetricHandler value.

type LongPollContextKey 

type LongPollContextKey struct{}

LongPollContextKey is the context key for a boolean stating whether the gRPC call is a long poll.

type Timer 

type Timer interface {
	// Record sets the timer value.
	Record(time.Duration)
}

Timer records time durations.

type TimerFunc 

type TimerFunc func(time.Duration)

TimerFunc implements Timer with a single function.

func (TimerFunc) Record 

func (t TimerFunc) Record(d time.Duration)

Record implements Timer.Record.
