   It is also possible to use "fastinter" and "downinter" to optimize delays
   between checks depending on the server state :
 
-             Server state            |             Interval used
-    ---------------------------------+-----------------------------------------
-     UP 100% (non-transitional)      | "inter"
-    ---------------------------------+-----------------------------------------
-     Transitionally UP (going down), |
-     Transitionally DOWN (going up), | "fastinter" if set, "inter" otherwise.
-     or yet unchecked.               |
-    ---------------------------------+-----------------------------------------
-     DOWN 100% (non-transitional)    | "downinter" if set, "inter" otherwise.

   Just as with every other time-based parameter, they can be entered in any
   other explicit unit among { us, ms, s, m, h, d }. The "inter" parameter also
