are you overriding this just to have correct type, if so I would rather do it differently by refactoring abstract class - something like this

export abstract class InstrumentationAbstract<T = types.InstrumentationConfig>
  implements types.Instrumentation {
  protected _config: T;
  constructor(
    public readonly instrumentationName: string,
    public readonly instrumentationVersion: string,
    config: T

It would require small refactoring of init method as well as InstrumentationModuleDefinition

export interface InstrumentationModuleDefinition<T = any> {

But then you would not have to worry about overriding the getConfig to have typed config from instrumentation class WDYT ?

I tried that a while ago but failed. typescript complained at various places like

  • the different default arguments in constructor of the concrete instrumentations
  • no compatible base type for registerInstrumentation() arguments.

There is already a stalled PR from @dyladan regarding this: #2388

My stalled PR was stalled because it was more difficult to get typescript to be happy than I anticipated when I started it. For now, I think doing it this way is probably fine.

I would like to make the types smarter eventually. I know it should be possible if someone has the time and inclination.
