Your Telemetry Has a Story - Write It Down

Many teams ship ambiguous, poorly defined telemetry that hides errors, fuels tribal knowledge, and slows down troubleshooting. This session shows how to design clear, consistent telemetry signals and validate them automatically. Drawing on OpenTelemetry Semantic Conventions, it covers practical patterns for naming metrics, spans, events, and their attributes, recording error information, plus a live demo of Weaver - a tool developed by OpenTelemetry community for documenting and enforcing telemetry schemas. These practices work just as well for Prometheus and legacy systems, proving how consistent, validated telemetry boosts reliability and cuts cognitive load.
