Hi , You mean to say after acknowledgement of first alert you are not getting alert after that . If the value crosses first time the range defined the alert would be generated but after that you have to acknowledge the alert first to get the second alert. Let me know if I am missing something.
Acknowledgement seems to work ok. The issue is related to the AlertReset event.
When the value=2 I expected to see an AlertReset event for the 0<=value<2 rule [Highlighted in blue] (I guess that if it would get logged it would have the 70053 ID that's missing [Highlighted in red])
