Documentation

Package otel contains an o11y.Provider that emits open telemetry gRPC. N.B. This has not been tried against a production collector, so we need to try it out on a safe / non production traffic service.

Functions

func New

func New(conf Config) (o11y.Provider, error)

Types

type Annotator

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

Annotator is a SpanProcessor that adds attributes to all started spans.

func (Annotator) ForceFlush

func (a Annotator) ForceFlush(context.Context) error

func (Annotator) OnEnd

func (a Annotator) OnEnd(s sdktrace.ReadOnlySpan)

func (Annotator) OnStart

func (a Annotator) OnStart(_ context.Context, s sdktrace.ReadWriteSpan)

func (Annotator) Shutdown

func (a Annotator) Shutdown(context.Context) error

type Config

type Config struct {
	Dataset            string
	GrpcHostAndPort    string
	HTTPHostAndPort    string
	ResourceAttributes []attribute.KeyValue

	SampleTraces  bool
	SampleKeyFunc func(map[string]any) string
	SampleRates   map[string]uint

	// DisableText prevents output to stdout for noisy services. Ignored if no other no hosts are supplied
	DisableText bool

	Test bool

	Writer  io.Writer
	Metrics o11y.ClosableMetricsProvider
}

type Provider

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

func (Provider) AddField

func (o Provider) AddField(ctx context.Context, key string, val any)

func (Provider) AddFieldToTrace

func (o Provider) AddFieldToTrace(ctx context.Context, key string, val any)

func (Provider) AddGlobalField

func (Provider) Close

func (o Provider) Close(ctx context.Context)

func (Provider) GetSpan

func (o Provider) GetSpan(ctx context.Context) o11y.Span

GetSpan returns the active span in the given context. It will return nil if there is no span available.

func (Provider) Helpers

func (Provider) Log

func (o Provider) Log(ctx context.Context, name string, fields ...o11y.Pair)

func (Provider) MetricsProvider

func (o Provider) MetricsProvider() o11y.MetricsProvider

func (*Provider) RawProvider

func (o *Provider) RawProvider() *Provider

RawProvider satisfies an interface the helpers need

func (Provider) StartSpan

func (o Provider) StartSpan(ctx context.Context, name string) (context.Context, o11y.Span)
