OpenCensus and OpenTracing have merged into OpenTelemetry!



TraceOptions is a byte on each OpenCensus span. Currently its last bit is set iff the span is sampled otherwise it is clear. Perhaps this table might help clarify better

State in hex State in binary Meaning
0x00 00000000 Span IS NOT sampled
0x01 00000001 Span IS sampled
