If you can live with them not being green, why don't you just disable 
all tests on the server ? They'll show up blue, but you will still have
access to all historical data, graphs etc.

You'd have to do some data extraction from the rrd files
(that's the only place historical performance data is stored),
and then apply your magical f() function to those data.

A slightly different approach is to use the "Metrics" report in Hobbit
and look at only the memory- and cpu-utilisation for a group of
hosts. It won't give you a report, but it may give you a hint of what
servers to look at.
