Variables ¶
var UseGLS = true
Use the legacy GLS way to forward spans using goroutine-local storage.
Functions ¶
func CurrentSpan
deprecated
added in
v1.5.7
func CurrentSpan() opentracing.Span
Returns the current span, or nil, if no span is currently set in local storage.
Deprecated: Start using the version with an explicit context parameter.
func CurrentSpanFromContextOrGLS ¶ added in v1.6.2
Returns the current span, or nil, if no span is currently set in local storage.
func NewPropagatingRoundTripper ¶ added in v1.5.7
func NewPropagatingRoundTripper(rt http.RoundTripper) http.RoundTripper
func TraceChild
deprecated
added in
v1.5.7
func TraceChildContext ¶ added in v1.6.0
func TraceChildContext(ctx context.Context, op string, fn func(ctx context.Context, span opentracing.Span) error) (err error)
Trace a child call while propagating the span using the context.
func TraceOrCreate
deprecated
added in
v1.5.7
func Tracing ¶ added in v1.5.7
func Tracing(service string, op string) startup_http.HttpMiddleware
Returns a middleware that adds tracing to an http handler. This will create a new and empty local storage for the current go routine to propagate the tracing context.
You can use the tracing middleware multiple time. Using it a second time will not start a new trace but will update 'service' and 'operation'.
func WithSpan
deprecated
added in
v1.5.7
func WithSpan(span opentracing.Span, fn func())
Runs the given function with the provided span set in local storage for the duration of function call. This method will not call 'Finish()' on the span
Deprecated: Please propagate spans using contexts.
Types ¶
type TracingOptions ¶
type TracingOptions struct {
Zipkin string `long:"zipkin" validate:"omitempty,url" description:"Zipkin server base url, an URL like http://host:9411/"`
Inputs struct {
// The service name of your application
ServiceName string `validate:"required"`
}
// contains filtered or unexported fields
}
func (*TracingOptions) Initialize ¶
func (opts *TracingOptions) Initialize()
