  • Method Details

    • alwaysOff

      static ComposableSampler alwaysOff()
      Returns a ComposableSampler that does not sample any span.

    • alwaysOn

      static ComposableSampler alwaysOn()
      Returns a ComposableSampler that samples all spans.

    • traceIdRatioBased

      static ComposableSampler traceIdRatioBased(double ratio)
      Returns a ComposableSampler that samples each span with a fixed ratio.

    • parentThreshold

      static ComposableSampler parentThreshold(ComposableSampler rootSampler)
      Returns a ComposableSampler that respects the sampling decision of the parent span or falls back to the given sampler if it is a root span.

    • getSamplingIntent

      SamplingIntent getSamplingIntent(io.opentelemetry.context.Context parentContext, String traceId, String name, io.opentelemetry.api.trace.SpanKind spanKind, io.opentelemetry.api.common.Attributes attributes, List<io.opentelemetry.sdk.trace.data.LinkData> parentLinks)
      Returns the SamplingIntent to use to make a sampling decision.

    • getDescription
