"No report" (purple) means that Hobbit is no longer getting updates for
this status. E.g. if you have a system with the Hobbit client installed
and the client is stopped, then after a while the client status messages
(cpu, disk, memory ...) will go purple. This usually indicates some sort
of error in the monitoring system.

"No data" (clear or white) means that this status has no meaningful data 
to report, but it IS being updated. There are two places where this is used: 

1) For client data which do not have any rules defined, e.g. the "procs" 
   column is reported as "no data" if there are no process checks, but
   Hobbit does get a "ps" listing.

2) For network tests that depend on each other, e.g. an "ssh" check will
   go "clear" if the "conn" (ping) test fails - because it doesn't make
   much sense reporting an "ssh" failure when it's really the whole box
   that is down.
