How to Use OpenTelemetry Span Builder — Construct, Validate, and Export OTel Spans
How to Use the OpenTelemetry Span Builder
Step 1: Name the Span
Enter a span name (e.g. http.server.request) and the service/tracer name that will create it.
Step 2: Choose a Span Kind
Pick INTERNAL, SERVER, CLIENT, PRODUCER, or CONSUMER to describe the span's role, following OpenTelemetry semantic conventions.
Step 3: Add Attributes and Events
Add key/value attributes (values are auto-typed as string, number, or boolean) and span events with their own optional attributes, such as cache.key=user:123, ttl=60.
Step 4: Pick an SDK
Select JavaScript (Node.js), Python, or Go to generate instrumentation code using each language's @opentelemetry/api, opentelemetry-api, or go.opentelemetry.io/otel package, including error recording and span status handling.
Step 5: Copy the Code
Copy the generated snippet and paste it into your service, adjusting the surrounding business logic as needed.
