Error Stack for Span Exporting

[DrewJKnowles]

Hi, I was wondering how I can attach/export an error stack that can be displayed on each trace?

In the console exporter it shows an error stack and message. I will like to simulate and export this information in my span as an attribute also.

Does anyone have an idea / way I can do so?

• This only affects the JavaScript OpenTelemetry library
• This may affect other libraries, but I would like to get opinions here first

somewhere some function that will catch error first

function onError() {
  // get active span
  const span = api.trace.getSpan(api.context.active());
  if (span) {
    // record exception
    span.recordException(err);
  } else {
    // no active span
  }
}
