Hello!

I am working with the new pipeline alarming scheme, but I can’t figure out how to do what I want it to do.

What I would like is:

If an alarm gets triggered it will send an email. If it clears itself and is re-triggered it will not send an email unless they acknowledged the first one. This way if an alarm goes off ten times at two in the morning (like if a sensor goes bad) they will only get one email.

I have tried looking at the alarm property ‘isAcked’ using an expression block. When I turn the alarm off and on again does it create a new instance? Is that why it can’t tell if it has been acknowledged?

Thanks,

Mike
