Otel Telemetry Emissions

Telemetry Emissions

A registry of what telemetry OpenTelemetry components actually emit, pinned to upstream versions.

Note: The telemetry emissions in these files were detected by LLM analysis of the upstream source and may contain errors. Verify against the component's source or docs before relying on a row for critical decisions.

Layout

<repo basename>/<path in repo>/v<version>.md

Example: opentelemetry-collector-contrib/receiver/kafkareceiver/v0.158.0.md

One file per scanned version. The files in a component directory are its telemetry history; index.md lists every file — start there to see what is covered.

Looking up a component at a version

1. Find the component's directory (or its row in index.md).
2. Pick the file matching the target version exactly.
3. If there is no exact match, use the file with the highest version below the target and say the exact version is unverified.
4. If the component or version is not covered at all, say so — do not infer telemetry from semantic conventions.

What a data file contains

Frontmatter (repo, path, version, scope_name, commit_sha, last_verified), then per-signal tables:

• Traces — span name, kind, attributes, notes
• Metrics — metric name, instrument type, unit, attributes, notes
• Logs — log/event name, attributes, notes

scope_name is the component's instrumentation scope — the anchor for matching runtime telemetry back to the component. Absent signals are omitted entirely. Notes marks conditional emission (feature gates, opt-in config, experimental semconv). Sources lists the upstream files the data came from.
