Functions

func ResourceServiceName

func ResourceServiceName(
	rsn primitives.ServiceName,
	envVars envVarLookup,
) string

ResourceServiceName returns the OpenTelemetry tracing service name for a Temporal service.

func SpanExportersFromEnv

func SpanExportersFromEnv(
	envVars envVarLookup,
) (map[SpanExporterType]otelsdktrace.SpanExporter, error)

SpanExportersFromEnv creates OTEL span exporters from environment variables.

Types

type ClientTraceInterceptor

type ClientTraceInterceptor grpc.UnaryClientInterceptor

ClientTraceInterceptor gives a named type to the grpc.UnaryClientInterceptor implementation provided by otelgrpc

func NewClientTraceInterceptor

func NewClientTraceInterceptor(
	tp trace.TracerProvider,
	tmp propagation.TextMapPropagator,
) ClientTraceInterceptor

NewClientTraceInterceptor creates a new gRPC client interceptor that tracks each request with an encapsulating span using the provided TracerProvider and TextMapPropagator.

type ExportConfig

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

ExportConfig represents YAML structured configuration for a set of OTEL trace/span/log exporters.

func (*ExportConfig) MetricExporters

func (ec *ExportConfig) MetricExporters() ([]metric.Exporter, error)

func (*ExportConfig) SpanExporters

func (ec *ExportConfig) SpanExporters() (map[SpanExporterType]otelsdktrace.SpanExporter, error)

func (*ExportConfig) UnmarshalYAML

func (ec *ExportConfig) UnmarshalYAML(n *yaml.Node) error

UnmarshalYAML loads the state of an ExportConfig from parsed YAML

type ServerTraceInterceptor

type ServerTraceInterceptor grpc.UnaryServerInterceptor

ServerTraceInterceptor gives a named type to the grpc.UnaryServerInterceptor implementation provided by otelgrpc

func NewServerTraceInterceptor

func NewServerTraceInterceptor(
	tp trace.TracerProvider,
	tmp propagation.TextMapPropagator,
) ServerTraceInterceptor

NewServerTraceInterceptor creates a new gRPC server interceptor that tracks each request with an encapsulating span using the provided TracerProvider and TextMapPropagator.

type SpanExporterType

type SpanExporterType string
