Here is an important distinction: There are 2 ways to functionally "disable"
active checks for a distributed nagios environment.

Actve_checks_enabled 0
  -or-
check_period none


I prefer the "check_period=none", as this means that the active checks are
still enabled, but never get scheduled.  Downside is they sit in your queue
taking up space (unfortunately, at the top of the queue too).

In some instances, the central server will never be able to perform the
active check, so  completely disabling the active check for those services
would be the way to go, and they won't go into the queue.
