Oracle Grid Control Notification for Data Guard failures Grid Control 10.2.0.5.

Does anyone know a way to configure a Grid Control notification rule for a failure of the SQL APPLY process on a logical standby database? I'd really like an email notification that the SQL APPLY process has encountered an error and is no longer applying redo to the logical standby.

I can get notifications on job failures, database down, listener stops, agent stops monitoring, but don't see how to get notified for this event.
Apply Lag will notify you when the apply is slow, not just when it has stopped.  This may give you too many notifications, but it seems like you could tweak the threshold to limit these.
