`typescript
const rootSpanOptions = { name: 'your root span' };
tracing.tracer.startRootSpan(rootSpanOptions, (rootSpan) => {
// You can create as many child spans as needed
childSpan = tracing.tracer.startChildSpan({
name: 'name of your child span'
});
// Do some operation...
// Finish the child span at the end of it's operation
childSpan.end();
// Finish the root span at the end of the operation
rootSpan.end();
});
