Turn off RED for PASSIVE ONLY checks?

[Emmett Hogan]

Ok....here's what I did:

- Set active_check to 1
- Set check_period to "none"
- Set active_checks_enabled to 1
- Set freshness_threshold to 120 seconds
- Set passive_checks_enabled to 1

According to Marc, if the "Status Data Age" is more than 2 minutes, the 
check_command should be run even though "check_period" is set to 
"none".  Do I have this right so far?  Well, this gets rid of the red on 
the TAC page since I don't have any active_checks disabled, but even 
though my "Status Data Age" is " 0d 8h 47m 26s" the active check is NOT 
being run. :-(
