From the answer you've given above it looks like a season change every night.
We are working on an AI feature which will have dynamic threshold capability for thresholds. If the anomalous behavior happens every night then our Anomaly Engine will learn this as a seasonality which will result in the alert noise reduction you want.
However, if its a new trend then we would monitor this for a certain period of time until we update our models. If not, we will consider them as temporary anomalies and would still be alerted.
This feature is being pushed out in phases to customers. You will soon be hearing about the feature in detail.
