> 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.
