This alert uses a dynamic predictive model to alert you when traffic anomalies are above or below the predictive model. The alert identifies both daily and weekly patterns in your CP code's traffic and uses them to make predictions that take into account normal cycles of the traffic over the course of a day or week. It can be set for only one CP code.

Here are the terms you need to know to configure the adaptive alert:

  • Anomaly — happens when the traffic exceeds the upper or lower alert’s threshold.
  • Deviation — a number of events when the traffic exceeds the threshold to become an anomaly. If set to 1, then if the traffic goes above or below the threshold just for one moment, it becomes the anomaly. If set to 2 or more, the traffic has to stay out of thresholds for a little longer to be considered an anomaly.
  • Polling cycle — 5 minute period.
  • Forgiving model — the alert is triggered less frequently, but some short anomalies aren’t detected.
  • Sensitive model — the alert is triggered more frequently, but it may be false positive.


Alert me when 4 anomalies
Over 3 deviations
happen in 5 polling cycles

Adaptive alarm will be triggered when 4 anomalies, each containing 3 consecutive deviations, occur within 25 minutes (5 x 5 minutes).

Notification time

  • New Alert - Up to five minutes since the detection of the condition.
  • Alert Cleared - The condition is cleared for 15 to 20 minutes.

Suppress a fired alert

Atypical traffic rates that occur during some events (for example, a sale or a major holiday) cause the firing of the Adaptive alert. If you don't want to be alerted about such traffic, you can suppress the alert.
