It will always provide the time period and filter boxes at the top of
the page, but should be displaying graphs below those fields if its
working correctly...

I don't believe there is one now, but I'll second that idea....

That looks good so far, I'll assume the templates themselves work.

Correct, this field is shown merely as an aid to building the dashboard.

I don't think you need any parenthesis on the Template Base, as
subpatterns from this match are not used anywhere.

I wonder if your problem is the ^ in your Row Name, since the
selection you're matching against is already a partial file name from
the template match.  Without looking at the code I could believe that
drraw is actually assembling a single regexp, not running one match
then a second match, which would mean you're putting a ^ in the middle
of a regexp.  Try just: datacenter.-(.*)

That seems more like what a Standard dashboard does, instead of a
grouped dashboard.   You didn't change the type by accident did you?
