Function: setSpanAttributes()

setSpanAttributes(attributes): void

Defined in: instrumentation.server.ts:1060

Set attributes on the currently active span.

Attributes provide contextual information about the operation represented by the span. They should be low-cardinality values suitable for grouping and filtering.

Parameters

attributes

TelemetryAttributes

Key-value pairs to attach to the span

Returns

void

Remarks

• Use semantic conventions where possible
• Avoid high-cardinality values (user IDs, timestamps, request IDs)
• Attributes can be used for filtering and grouping in observability tools
• If no span is active, this is a no-op (safe to call)

Example

setSpanAttributes({
  'http.method': 'POST',
  'http.status_code': 201,
  'user.authenticated': true,
});
