Types

type ClientHandler

type ClientHandler struct{}

ClientHandler is otel ClientHandler

func (*ClientHandler) HandleConn

func (c *ClientHandler) HandleConn(ctx context.Context, cs stats.ConnStats)

HandleConn exists to satisfy gRPC stats.Handler.

func (*ClientHandler) HandleRPC

func (c *ClientHandler) HandleRPC(ctx context.Context, rs stats.RPCStats)

HandleRPC implements per-RPC otel and stats instrumentation.

func (*ClientHandler) TagConn

func (c *ClientHandler) TagConn(ctx context.Context, cti *stats.ConnTagInfo) context.Context

TagConn exists to satisfy gRPC stats.Handler.

func (*ClientHandler) TagRPC

func (c *ClientHandler) TagRPC(ctx context.Context, rti *stats.RPCTagInfo) context.Context

TagRPC implements per-RPC context management.

type Option

type Option func(*options)

Option is otel option.

func WithPropagator

func WithPropagator(propagator propagation.TextMapPropagator) Option

WithPropagator with tracer propagator.

func WithTracerProvider

func WithTracerProvider(provider trace.TracerProvider) Option

WithTracerProvider with tracer provider. Deprecated: use otel.SetTracerProvider(provider) instead.

type Tracer

NewTracer create tracer instance

func (*Tracer) End

func (t *Tracer) End(ctx context.Context, span trace.Span, m interface{}, err error)

End finish otel span

func (*Tracer) Start

func (t *Tracer) Start(ctx context.Context, operation string, carrier propagation.TextMapCarrier) (context.Context, trace.Span)

Start start otel span
