Availability Groups and backup alarms

I have read through some of the discussions of how to handle alarms for database backups with Availability Groups but still have not solved my issue.  I do backups from the Primary replica in the Availability Group.  When my AG fails over, I get alarms for my databases that they have not been backed up in so many days.  They have been backed up, only on the other replica.  How do I handle this in Spotlight?
