Hi.
I’m trying to create a new alert, but always return “no data” message. The query is working and returning data normally. How to create an alert properly? Some screen shots:
Test rule result:

You’re getting data. I don’t see the No Data error in the UI.
Try setting the For field to something lower. Right now, you’ll only get the alert if it is firing for a full 2 minutes.
