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) AddSampleWithLabels ¶
func (Blackhole) IncrCounter ¶
func (Blackhole) IncrCounterWithLabels ¶
func (Blackhole) MeasureSinceWithLabels ¶
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).
type DogStatsdConfig ¶
type FileConfig ¶
type FileConfig struct { Prometheus *PrometheusConfig `hcl:"Prometheus"` DogStatsd []DogStatsdConfig `hcl:"DogStatsd"` Statsd []StatsdConfig `hcl:"Statsd"` M3 []M3Config `hcl:"M3"` InMem *InMem `hcl:"InMem"` UnusedKeys []string `hcl:",unusedKeys"` }
type Label ¶
type Label = metrics.Label
Label is a label/tag for a metric
func SanitizeLabels ¶
SanitizeLabels sanitize all given labels
type Metrics ¶
type Metrics interface { // A Gauge should retain the last value it is set to SetGauge(key []string, val float32) SetGaugeWithLabels(key []string, val float32, labels []Label) // Should emit a Key/Value pair for each call EmitKey(key []string, val float32) // Counters should accumulate values IncrCounter(key []string, val float32) IncrCounterWithLabels(key []string, val float32, labels []Label) // Samples are for timing information, where quantiles are used AddSample(key []string, val float32) AddSampleWithLabels(key []string, val float32, labels []Label) // A convenience function for measuring elapsed time with a single line MeasureSince(key []string, start time.Time) MeasureSinceWithLabels(key []string, start time.Time, labels []Label) }
