Functions

func AddMeterConfigSchema added in v0.0.36 

func AddMeterConfigSchema(c interface {
	AddResource(url string, r io.Reader) error
}) error

AddMeterConfigSchema adds the meter schema to the compiler. The interface is specified instead of `jsonschema.Compiler` to allow the use of any jsonschema library fork or version.

func AddTracerConfigSchema added in v0.0.33 

func AddTracerConfigSchema(c interface {
	AddResource(url string, r io.Reader) error
}) error

AddTracerConfigSchema adds the tracer schema to the compiler. The interface is specified instead of `jsonschema.Compiler` to allow the use of any jsonschema library fork or version.

func End 

func End(span trace.Span, err *error)

End finishes span, and automatically sets the error state if *err is not nil or during panicking.

Usage: 

func Divide(ctx context.Context, numerator, denominator int) (ratio int, err error) {
	ctx, span := tracer.Start(ctx, "my-operation")
	defer otelx.End(span, &err)
	if denominator == 0 {
		return 0, errors.New("cannot divide by zero")
	}
	return numerator / denominator, nil
}

func SetupJaegerTracer added in v0.0.33 

func SetupJaegerTracer(tracerName string, c *TracerConfig) (trace.Tracer, propagation.TextMapPropagator, error)

Optionally, Config.Providers.Jaeger.LocalAgentAddress can be set. NOTE: If Config.Providers.Jaeger.Sampling.ServerURL is not specfied, AlwaysSample is used.

func SetupOTLPMeter added in v0.0.36 

func SetupOTLPMeter(meterName string, c *MeterConfig) (metric.Meter, error)

func SetupOTLPTracer added in v0.0.33 

func SetupOTLPTracer(tracerName string, c *TracerConfig) (trace.Tracer, propagation.TextMapPropagator, error)

func SetupPrometheusMeter added in v0.0.36 

func SetupPrometheusMeter(meterName string, c *MeterConfig) (metric.Meter, error)

func SetupStdoutMeter added in v0.0.36 

func SetupStdoutMeter(meterName string, c *MeterConfig) (metric.Meter, error)

func SetupStdoutTracer added in v0.0.33 

func SetupStdoutTracer(tracerName string, c *TracerConfig) (trace.Tracer, propagation.TextMapPropagator, error)

func StringAttrs 

func StringAttrs(attrs map[string]string) []attribute.KeyValue

func WithSpan 

func WithSpan(ctx context.Context, name string, f func(context.Context) error, opts ...trace.SpanStartOption) (err error)

WithSpan wraps execution of f in a span identified by name.

If f returns an error or panics, the span status will be set to the error state. The error (or panic) will be propagated unmodified.

f will be wrapped in a child span by default. To make a new root span instead, pass the trace.WithNewRoot() option.
