Hi There,
You should try like this:
The type of property to monitor is : APM - Application
Trigger alert when all of the following apply
Node Status is equal to up
Application name is equal to XXXXXXXXX
Trigger alert when any of thr apply:
Application status is equal to Down
Application status is equal to unknown

Let me know how it goes into your environments.
