Yes. Each time Nagios generates a notification for any state, the notification
count is incremented.  After the recovery (OK state) notification is sent, the
count is reset to 0.

All the warning notifications incremented the count, so the count was greater 
than 3 when the the service went critical.  There is no way to specify the 3rd 
CRITICAL notification with escalations.  Notification counts do not take the 
state into account.

You might re-think why you want to do this.  If there has been a problem at 
the warning level for 2 or more notification intervals without it being 
acknowledged (which stops notifications) or fixed, maybe your secondary 
contact should be notified anyway when the critical threshold is exceeded.

If you really want it to work the way you describe then the best solution I 
can think of is to have 2 separate services with different contacts.  One that 
issues only warnings and the other only critical problems.  But then you've 
doubled the number of checks you are doing for the same problem.
