SCOM 2012 sp1 Resolving Heartbeat Alerts.

 Hi!

I want to get email alerts when Computer Unreachable (windows clients with scom agents). In that guide http://technet.microsoft.com/en-us/library/hh212798.aspx I can not find Health Service Heartbeat Failure and Computer Not Reachable monitors for override them to class Windows clinets with scom agents. Could you tell me step-by-step how can I make this email notification. Thank you!
