Functions ¶
func ContextWithSpan ¶
func SpanFromContext ¶
func StartChild ¶
func StartChild(parent opentracing.Span, operation string) (span opentracing.Span)
func StartChildFromContext ¶
func StartChildFromContext(ctx context.Context, operation string, opts ...opentracing.StartSpanOption) (span opentracing.Span)
StartChildFromContext starts and returns a Span with `operation`, using any Span found within `ctx` as a ChildOfRef. If no such parent could be found, StartChildFromContext creates a root (parentless) Span.
Example usage:
SomeFunction(ctx context.Context, ...) {
sp := trace.StartChildFromContext(ctx, "SomeFunction")
defer sp.Finish()
...
}
func StartFollow ¶
func StartFollow(follow opentracing.Span, operation string) (span opentracing.Span)
func StartServer ¶
func StartServer(operation string, format, carrier interface{}) opentracing.Span
StartServer extracts SpanContext from carrier, then starts and returns a server Span with `operation`, using any Span found within `SpanContext` as a ChildOfRef. If no such parent could be found, StartChildFromContext creates a root (parentless) Span.
Example usage:
SomeFunction(ctx context.Context, ...) {
sp := trace.StartServer("SomeFunction", trace.HTTPHeaders, opentracing.HTTPHeadersCarrier(r.Header))
defer sp.Finish()
...
}
Types ¶
type HTTPHeadersCarrier ¶
type HTTPHeadersCarrier = opentracing.HTTPHeadersCarrier
type StartSpanOption ¶
type StartSpanOption = opentracing.StartSpanOption
type TextMapCarrier ¶
type TextMapCarrier = opentracing.TextMapCarrier
type Tracer ¶
type Tracer struct {
opentracing.Tracer
// contains filtered or unexported fields
}
func (*Tracer) Extract ¶
func (t *Tracer) Extract(format, carrier interface{}) opentracing.SpanContext
Extract() returns a SpanContext instance given `format` and `carrier`. If there was simply no SpanContext to extract or errors occurred, Extract() returns nil.
func (*Tracer) Inject ¶
func (t *Tracer) Inject(sc opentracing.SpanContext, format, carrier interface{})
func (*Tracer) StartChild ¶
func (*Tracer) StartChildFromContext ¶
func (t *Tracer) StartChildFromContext(ctx context.Context, operation string, opts ...opentracing.StartSpanOption) opentracing.Span
StartChildFromContext starts and returns a Span with `operation`, using any Span found within `ctx` as a ChildOfRef. If no such parent could be found, StartChildFromContext creates a root (parentless) Span.
Example usage:
SomeFunction(ctx context.Context, ...) {
sp := trace.StartChildFromContext(ctx, "SomeFunction")
defer sp.Finish()
...
}
func (*Tracer) StartFollow ¶
func (*Tracer) StartServer ¶
StartServer extracts SpanContext from carrier, then starts and returns a server Span with `operation`, using any Span found within `SpanContext` as a ChildOfRef. If no such parent could be found, StartChildFromContext creates a root (parentless) Span.
Example usage:
SomeFunction(ctx context.Context, ...) {
sp := trace.StartServer("SomeFunction", trace.HTTPHeaders, opentracing.HTTPHeadersCarrier(r.Header))
defer sp.Finish()
...
}
