Workers - Workers tracing , new getActiveSpan(), recordException(), startSpan(), and setAttributes() APIs

UpdateSep 25, 20262d2 days ago·Unverified·Added Sep 26, 2026

Custom spans in Workers now support more of the OpenTelemetry span API, so you can instrument more of your code and record errors directly on your spans. tracing.startSpan(name) creates a span without making it the active span, and returns it. Other spans do not nest under it. Call span.end() when the operation is complete.
