Functions ¶
func AddNewTagKey ¶
AddNewTagKey adds new tag keys to existing view
func AddTagKeyToCtx ¶
AddTagKeyToCtx assigns opencensus tag key value to context
func GetTraceSamplingRate ¶
GetTraceSamplingRate parses the given rate and returns the parsed rate
func IsTracingEnabled ¶
IsTracingEnabled parses the given rate and returns false if sampling rate is explicitly set 0
func NewMeasureView ¶
func NewMeasureView(measure stats.Measure, keys []tag.Key, aggregation *view.Aggregation) *view.View
NewMeasureView creates opencensus View instance using stats.Measure
func SpanFromContext ¶
SpanFromContext returns the SpanContext stored in a context, or nil if there isn't one.
func SpanToFastHTTPContext ¶
func SpanToFastHTTPContext(ctx *fasthttp.RequestCtx, span *trace.Span)
SpanToFastHTTPContext sets span into fasthttp.RequestCtx.
func TraceSampler ¶
func TraceSampler(samplingRate string) trace.StartOption
TraceSampler returns Probability Sampler option.
Types ¶
type StdoutExporter ¶
type StdoutExporter struct{}
StdoutExporter is an open census exporter that writes to stdout.
func (*StdoutExporter) ExportSpan ¶
func (e *StdoutExporter) ExportSpan(sd *trace.SpanData)
ExportSpan implements the open census exporter interface
