So, I have 16 critical parameters that I am evaluating for outside normal operating range. Each Parameter has a Critical Min, Target Min, Target Max, and Critical Max. In an effort to be efficient, I would like to create a single notification, that would trigger any time any of the Alarm Status attributes <> OK. So, I have created a single element with all of the PI tags (pic1), and their associated child elements. And I have tried creating child elements with the various items (pic2). Analysis is in pic3. And the single notification I would like to send is in pic4.
The problems becomes how to create a trigger. It should trigger anytime, any of the Alarm Status words become <> OK. I would also like to put the offending parameter in the subject line of the notification.
Seems like no matter what I attempt, I just can't come up with the correct incantation.
Also, I am using pre-PI2010. So, each notification costs 7 PI tags. If I create a separate notification for each of the 16, I consume 112 tags, plus have to maintain 16 notifications, if there is a change.
