summary
OpenTelemetry marks the database semantic conventions as a stable release candidate and defines about 15 attributes for database spans; metrics are still under development. Example uses a React frontend with a Node backend, Postgres, and auto-instrumentation with Postgres client sending traces to Grafana (or a console exporter). Traces show separate connect and statement spans; operation duration metrics reveal inserts/deletes slower than selects. Default instrumentation sanitizes query arguments and requires opt-in to send raw queries.
