Functions

func EmitVersion 

func EmitVersion(m Metrics)

Types

type Blackhole 

type Blackhole struct{}

Blackhole implements the Metrics interface, but throws away the metric data Useful for satisfying the Metrics interface when testing code which depends on it.

func (Blackhole) AddSample 

func (Blackhole) AddSample(key []string, val float32)

func (Blackhole) AddSampleWithLabels 

func (Blackhole) AddSampleWithLabels(key []string, val float32, labels []Label)

func (Blackhole) EmitKey 

func (Blackhole) EmitKey(key []string, val float32)

func (Blackhole) IncrCounter 

func (Blackhole) IncrCounter(key []string, val float32)

func (Blackhole) IncrCounterWithLabels 

func (Blackhole) IncrCounterWithLabels(key []string, val float32, labels []Label)

func (Blackhole) MeasureSince 

func (Blackhole) MeasureSince(key []string, start time.Time)

func (Blackhole) MeasureSinceWithLabels 

func (Blackhole) MeasureSinceWithLabels(key []string, start time.Time, labels []Label)

func (Blackhole) SetGauge 

func (Blackhole) SetGauge(key []string, val float32)

func (Blackhole) SetGaugeWithLabels 

func (Blackhole) SetGaugeWithLabels(key []string, val float32, labels []Label)

type CallCounter 

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

CallCounter is used to track timing and other information about a "call". It is intended to be scoped to a function with a defer and a named error value, if applicable, like so: 

func Foo() (err error) {
    call := StartCall(metrics, "foo")
    defer call.Done(&err)

    call.AddLabel("food", "burgers")
}

See `Done` doc for labels automatically added.

Instances of this struct should only be created directly by this package and its subpackages, which define the specific metrics that are emitted. It is left exported for testing purposes.

func StartCall 

func StartCall(metrics Metrics, key string, keyn ...string) *CallCounter

StartCall starts a "call", which when finished via Done() will emit timing and error related metrics.

func (*CallCounter) AddLabel 

func (c *CallCounter) AddLabel(name, value string)

AddLabel adds a label to be emitted with the call counter. It is safe to call from multiple goroutines.

func (*CallCounter) Done 

func (c *CallCounter) Done(errp *error)

Done finishes the "call" and emits metrics. No other calls to the CallCounter should be done during or after the call to Done. In other words, it is not thread-safe and is intended to be the final call to the CallCounter struct. Emits latency and counter metrics, including adding a Status label according to gRPC code of the given error. If nil error, the code is OK (success).
