interface ISpan
Since 0.2.0

A span represents a single operation within a trace.

Methods

setAttribute(
key: string,
): this

Sets a single attribute on the span.

setAttributes(attributes: Readonly<Record<string, SpanAttributeValue>>): this

Sets multiple attributes on the span.

setStatus(status: SpanStatus): void

Sets the status of the span.

recordException(error: Error): void

Records an exception on this span.

end(): void

Ends the span. Must be called exactly once.

Since 0.2.0
spanContext(): SpanContext

Returns the span's context (traceId, spanId, traceFlags).

Used by the middleware to inject the span's own traceparent into the response header so downstream hops see this server span as the parent.

import { type ISpan } from "telemetry-plugin/src/index.ts";
