> GroupMetadataManager includes quite a few gauges that look very useful! NumGroups, NumGroupsPreparingRebalance, NumGroupsStable, NumGroupsDead, NumGroupsEmpty.
> I couldn't find them in our site-docs, but they seem quite useful and will be nice to include. 
> LastStableOffsetLag is also missing, but I'm not sure if it is useful enough to include.
