Research question and boundary

Distributed Tracing Sampling Bias Study asks how head, tail, error, latency, and service-specific sampling rules alter the incidents visible to reviewers. Stage 1, research question and boundary, declares one eligible request across trace decision, service hops, logs, metrics, error state, retention, and incident linkage as the observation unit and freezes population, system boundaries, local and UTC times, source versions, inclusion rules, exclusions, and intended decision before outcomes are reviewed. Record DO-R-1013-01 distinguishes system events, engineering interpretations, owner decisions, implementation evidence, and unresolved hypotheses. This prospective protocol reports no completed client outcomes and defines no universal performance benchmark.

At stage 1 for Distributed Tracing Sampling Bias Study, include routine, missing-source, wrong-identity, conflicting-version, late-arriving, inaccessible-system, unavailable-owner, reversed, corrected, reverted, and reopened cases. Two reviewers classify a stratified subset independently using written anchors, preserve first-pass disagreement, and adjudicate against retained evidence. Report numerator, denominator, exclusions, null values, age bands, correction rate, disagreement, and residual cases together. Alternative explanations include configuration, case mix, cache state, clock drift, synchronization, sampling, ownership changes, release versions, seasonality, and selection effects. The ten public sources guide control design but do not inspect this system, establish causation, certify a provider, or authorize deployment. Preserve protocol, queries, codebook, fixtures, sample receipt, chronology, reviewer notes, decision log, approved action, verification, limitations, and refresh trigger so another authorized engineer can reproduce the bounded result without retaining secrets or unnecessary production data.
