When using `@Span`, would it make sense to be able to add the args that a method was called with as span tags?

[hhedger-ae]

Just discovered @span and the module options to add spans to all providers and controllers and I'm really excited about it.

When debugging, I feel like it'd be useful to be able to see what arguments a wrapped method was called with via span tags. Any thoughts on this?

Something like:

DatadogTraceModule.forRoot({ controllers: true, providers: true, includeArgs: true })

or @Span({ includeArgs: true })

I'm still fairly new to DataDog, so I don't know if this would be a mistake or not. Thanks for your work on this!

I assume here https://github.com/codebrick-corp/nestjs-ddtrace/blob/main/src/decorator.injector.ts#L127

You'd add something that was essentially

if (includeArgs) {
  span.setTag('args', args)
}
