Functions

func DebugMode

func DebugMode() bool

func IsEnabled

func IsEnabled(tp trace.TracerProvider) bool

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 ClientStatsHandler

type ClientStatsHandler stats.Handler

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

func NewClientStatsHandler

func NewClientStatsHandler(
	tp trace.TracerProvider,
	tmp propagation.TextMapPropagator,
) ClientStatsHandler

NewClientStatsHandler creates a new gRPC stats handler that tracks each request with an encapsulating span using the provided TracerProvider and TextMapPropagator.

NOTE: If the TracerProvider is `noop.TracerProvider`, it returns `nil`.

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 ServerStatsHandler

type ServerStatsHandler stats.Handler

ServerStatsHandler gives a named type to the stats.Handler implementation provided by otelgrpc.

func NewServerStatsHandler

func NewServerStatsHandler(
	tp trace.TracerProvider,
	tmp propagation.TextMapPropagator,
	logger log.Logger,
) ServerStatsHandler

NewServerStatsHandler creates a new gRPC stats handler that tracks each request with an encapsulating span using the provided TracerProvider and TextMapPropagator.

NOTE: If the TracerProvider is `noop.TracerProvider`, it returns `nil`.

type SpanExporterType

type SpanExporterType string
