Interface Monitoring Using PE's and Notifications

I am trying to monitor an interface to insure it is running OK.  There are two things that I am trying to get to work.

 

I have set up two health tags for the interface: "Device Status" and "Heartbeat"

 

In notifications I have set up a trigger that alarms if "Device Status" <> "Good".  This seems to work.

 

The other thing I am trying to get setup is if the heartbeat become stale.  To do this I have created a PE tag that I will us in notifications, it looks like like this:

 

prevval('heartbeat', '*') = 'heartbeat' 

 

The PE is schedule to execute every 30 seconds.

 

My PE is not working, it is always returning 1, so I must be missing something.  It seems like the previous value should never equal the current value.

 

Any help would be appreciated.  Also if there are any suggestions on a better way to do this I'm open to ideas, I a novice when it comes to working with interface health points.
