Add the eBPF side of basic samplers implementation:
traceIDRatio,ParentBased,AlwaysOnandAlwasyOff.Basic testing I did with the
httpPlusDbexample:I used a test script that calls the endpoint of the application 1000 times.
Using
OTEL_TRACES_SAMPLER=always_onUsing
OTEL_TRACES_SAMPLER=parentbased_traceidratio, OTEL_TRACES_SAMPLER_ARG=0.1Using
OTEL_TRACES_SAMPLER=parentbased_traceidratio, OTEL_TRACES_SAMPLER_ARG=0.01Split from #971
Part of #953
