Enum opentelemetry::sdk::trace::sampler::Sampler

pub enum Sampler {
    Always,
    Never,
    Parent,
    Probability(f64),
}

Sampling options

Variants

Always

Always sample the trace

Never

Never sample the trace

Parent

Sample if the parent span is sampled

Probability(f64)

Sample a given fraction of traces. Fractions >= 1 will always sample. If the parent span is sampled, then it's child spans will automatically be sampled. Fractions < 0 are treated as zero, but spans may still be sampled if their parent is.

Trait Implementations
