It is looking good. A few notes.
Ackers (__acker) are not spouts. They are bolts (but it might be nice to
distinguish between system bolts and other bolts)
Ackers are not showing any instances even when there are some.
The System Bolt (__system) is a bolt but not really, and probably does not
need to show up here at all. It is created as a way to collect metrics and may
go away in the future.
