> I had added these without much thought when writing the metrics-framework to
> test out the concept.
> Looking back, these actually need of more investigation, as some are actually
> wrong or at least do not add much value. Wrong is the active-transaction, as
> actually each ObjectStore is a thread-local, and an aggregate number is what
> was meant. Open/committed/rollback need some investigation what really helps.
> Goal is to remove these before the release to reduce confusion to users.
