Using Kafka and Grafana to monitor meteorological conditions @utkarshcmu @torkelo does this support : If we can have consensus on any one implementation, I can work on a PR. That is not correct, if any series passes the condition test the alert will fire. I would like this even if only to implement an OUTSIDE range using max() for upper limit and min() for lower limit atm with the AND logic you can only do a fudgey INSIDE RANGE.
