Tracing Exporters

Tracing Exporters are OpenTelemetry exporter wrappers for Dapr. The actual export implementations should be contributed to the OpenTelemetry repository.

Currently supported exporters are:

• Native

  OpenTelemetry default exporter

• String

  Export to a string buffer. This is mostly used for testing purposes.

• Zipkin

  Export to a Zipkin back-end.

Implementing a new Exporter wrapper

A compliant exporter wrapper needs to implement one interface: Exporter, which has a single method:

type Exporter interface {
	Init(daprID string, hostAddress string, metadata Metadata) error
}

The implementation should configure the exporter according to the settings specified in the metadata.

Types

type Exporter

type Exporter interface {
	Init(daprID string, hostAddress string, metadata Metadata) error
}

Exporter is the interface for tracing exporter wrappers

type Metadata

type Metadata struct {
	Properties map[string]string `json:"properties"`
	Buffer     *string           `json:"-"`
}

Metadata represents a set of exporter specific properties
