Can a notification be triggered on a timestamp? I would like to be notified if an hourly accumulator number is not recieved. If notification could access the last time a snapshot I think I could trigger on the timestamp.
You can use a PE logical syntax to check if there has been a lapse of more than 60 minutes between two events and then use this to configure an instance of notification:
prevevent('test_point1','* ')<'* -60m'
Please also check this KB article for several more examples of this sort to monitor tag health. You may be especially interested in the section titled "Calculations and notifications".
