interesting idea.
i wonder if the tree could represent this, and if it would require some 
refresh for status to update.

i wonder if the scheme should be based on status of entities, which 
requires specific logic, or on some sort of an alert like mechanism 
(since alerts are similar to "problems" which you describe above).
then you can leverage the fact events/alerts include all entities in the 
hierarchy, so very easy to highlight an entity as with an 
"issue/alert/problem" based on it having any open alerts/problems.
