Package io.opentelemetry.contrib.awsxray

Class AlwaysRecordSampler

java.lang.Object

io.opentelemetry.contrib.awsxray.AlwaysRecordSampler

All Implemented Interfaces:

io.opentelemetry.sdk.trace.samplers.Sampler

@Immutable
public final class AlwaysRecordSampler
extends Object
implements io.opentelemetry.sdk.trace.samplers.Sampler

This sampler will return the sampling result of the provided rootSampler, unless the sampling result contains the sampling decision SamplingDecision.DROP, in which case, a new sampling result will be returned that is functionally equivalent to the original, except that it contains the sampling decision SamplingDecision.RECORD_ONLY. This ensures that all spans are recorded, with no change to sampling.

The intended use case of this sampler is to provide a means of sending all spans to a processor without having an impact on the sampling rate. This may be desirable if a user wishes to count or otherwise measure all spans produced in a service, without incurring the cost of 100% sampling.
