The "Zen" of Python Exemplars
summary
Exemplars attach trace IDs to metric points so a dashboard diamond links directly to a trace; example setup sends OpenTelemetry traces to Jaeger and Prometheus-instrumented metrics to Prometheus, adding a zero‑padded hex trace ID (and optional trace URL) into the exemplar. OpenTelemetry’s metric spec includes exemplars but Python OTel SDK lacks exemplar support today, Prometheus stores exemplars behind a feature flag and only supports them on counters and histograms, and cloud managed Prometheus implementations vary. Exemplars speed trace onboarding but are not a silver bullet.
