If the corresponding host is down or unreachable, the service will go
immediately in to a hard state (but the notification sent should be a
host notification not a service notification).

Nagios will display warning, critical etc, states on screen as soon as
a check returns that state.  The max_check_attempts only affects when
it will send a notification (email usually) or trigger an event
handler and so on (when it goes from a soft to a hard state).

Note that by default, the numbers for normal_check_interval and
retry_check_interval are in minutes, not seconds.  This is set by the
interval_length directive in your nagios.cfg file.  I recommend
keeping it that way.  So.. in your service definition, you probably
need:

        normal_check_interval   5   ; 5 minutes
        retry_check_interval      1   ; 1 minute

See:
http://nagios.sourceforge.net/docs/3_0/configmain.html#interval_length

For more information on hard and soft states, see:

http://nagios.sourceforge.net/docs/3_0/statetypes.html

I hope that helps,

Jim
