Functions

func InstallNewPipeline

func InstallNewPipeline(config Config) (*push.Controller, error)

InstallNewPipeline instantiates a NewExportPipeline and registers it globally. Typically called as:

pipeline, err := dogstatsd.InstallNewPipeline(dogstatsd.Config{...})
if err != nil {
	...
}
defer pipeline.Stop()
... Done

func NewExportPipeline

func NewExportPipeline(config Config, period time.Duration) (*push.Controller, error)

NewExportPipeline sets up a complete export pipeline with the recommended setup, chaining a NewRawExporter into the recommended selectors and batchers.

Types

type Config

type Config = statsd.Config

type Exporter

type Exporter struct {
	*statsd.Exporter
	*statsd.LabelEncoder

	ReencodedLabelsCount int
}

Exporter implements a dogstatsd-format statsd exporter, which encodes label sets as independent fields in the output.

func NewRawExporter

func NewRawExporter(config Config) (*Exporter, error)

NewRawExporter returns a new Dogstatsd-syntax exporter for use in a pipeline. This type implements the metric.LabelEncoder interface, allowing the SDK's unique label encoding to be pre-computed for the exporter and stored in the LabelSet.

func (*Exporter) AppendName

func (*Exporter) AppendName(rec export.Record, buf *bytes.Buffer)

AppendName is part of the stats-internal adapter interface.

func (*Exporter) AppendTags

func (e *Exporter) AppendTags(rec export.Record, buf *bytes.Buffer)

AppendTags is part of the stats-internal adapter interface.
