Functions

func DoInSpan

func DoInSpan(ctx context.Context, operationName string, doFn func(context.Context), opts ...otelTrace.SpanStartOption)

DoInSpan executes function doFn inside new span with `operationName` name and hooking as child to a span found within given context if any. It uses opentracing.Tracer propagated in context. If no found, it uses noop tracer notification.

func DoWithSpan

func DoWithSpan(ctx context.Context, operationName string, doFn func(context.Context, otelTrace.Span), opts ...otelTrace.SpanStartOption)

DoWithSpan executes function doFn inside new span with `operationName` name and hooking as child to a span found within given context if any. It uses opentracing.Tracer propagated in context. If no found, it uses noop tracer notification.

func InitTracerFromEnv

func InitTracerFromEnv(logger *log.Logger, serviceName string, attrs ...attribute.KeyValue) error

InitTracerFromEnv init opentelemetry tracer by env.
