Creating a Child Span with OpenTelemetry in TypeScript

const tracer = opentelemetry.trace.getTracer('example-basic-tracer-node')

  const span = tracer.startSpan('say-hello')
  span.setAttribute('hello-to', 'world')
  span.addEvent('invoking say-hello', { 'hello-to': 'world' })

  await Effect.gen(function* () {
    yield* Effect.sleep(1000)
  }).pipe(Effect.withSpan('fetch-todo'), executePromiseEffect)

  span.end()
