Description
Based on the discussion and investigation in #1396, it has become apparent that dropping these particular metrics might become problamatic for users of certain environments who have come to depend on them.
We believed when making the change, that the info provided by these metrics would still be available at a slice level. However in some cases (docker driver?) this appears not to be the case.
As per #1396 (comment) the original change should have been valid but given that it can cause issues, this change reverts the drop.
