Package io.opentelemetry.contrib.sampler

Class LinksBasedSampler

java.lang.Object

io.opentelemetry.contrib.sampler.LinksBasedSampler

All Implemented Interfaces:

io.opentelemetry.sdk.trace.samplers.Sampler

public final class LinksBasedSampler
extends Object
implements io.opentelemetry.sdk.trace.samplers.Sampler

A Sampler that uses the sampled flag of the span links if present. If at least one span link is sampled, then this span will be sampled. Otherwise, it is not sampled. If the span has no span links, this Sampler will use the "root" sampler that it is built with.
