Problem notification with new anomaly detection App

[andreaCaria]

Hi everyone,

I have just created an anomaly detection rule using a DQL query and the Davis Analyzer, starting from this dashboard tile.

As you can see, there are three simulated alerts, therefore the detection condition is met.

The problem is that I can’t find this alert either in the Problems section or as a dt.davis.event / dt.davis.problem.

Our goal is to notify users whenever this condition is met.

Is there anything I can do to achieve this?

Thanks a lot,

Andrea

Hi,

Maybe it is an issue in the evaluation window time. I would open a support ticket.

Best regards

Hi, thanks a lot. We identified an issue related to the evaluation window time. Specifically, when a sliding window of 1 minute is configured, the davis.event is not generated and the problem is not raised. When the window is set to values greater than 2 minutes, the detection works as expected.

Hi,
IMO  this behavior is expected and it’s not a bug.
The key point is that “Simulated alerts” shown from a dashboard/notebook context are simulation results, not production alerts. Dynatrace explicitly describes this as Notebook & Dashboard Simulation in Davis AI limits (simulation per Davis analyzer execution).
https://docs.dynatrace.com/docs/discover-dynatrace/platform/davis-ai/reference/davis-ai-limits

These simulated alerts only confirm that the detection logic would have triggered on historical data.
Because it’s a simulation/validation run, it won’t necessarily create Problems or corresponding dt.davis.problem / dt.davis.event entries.

When you create an anomaly detection rule from a dashboard tile / DQL Analyzer, Davis runs in simulation mode only.
Simulation is not production alerting.
Yoiu should try turn your DQL result into a metric and then use Metric events (custom alerts)
