otel_sampler_parent_based (opentelemetry v1.6.0)

View Source

An otel_sampler that makes the decision based on the parent.

This sampler decides with the following possibilities:

  1. a remote parent that is sampled (by default always_on);
  2. a remote parent that is not sampled (by default always_off);
  3. a local parent that is sampled (by default always_on);
  4. a local parent that is not sampled (by default always_off);
  5. no parent (by default always_on).

For each of these cases a different sampler can be configured. For options, see opts().

This is one of the built-in samplers provided by the OpenTelemetry SDK.
