APPLICATION is the term used in Prognosis which is a logical group that can group entities into one entity.
First set up all the entities you are going to monitor in your Application:
e.g.
PROCEXE ADDEXE (SNIPPINGTOOL)
PORT ADDPORT (135)
Then group it all together in a group call 'Windows'
APPLICATION ADDEXE ( "Windows", SNIPPINGTOOL,1)
APPLICATION ADDPORT ( "Windows", 135,ACTIVE,1)
The number 1 represents the number of instances measured for availability.
