Filtering the Anomaly Detection report by the top-N anomalies

Optionally, you can configure the report to display a selected number of the topmost anomalies, which are based on the absolute value of the calculated deviation.

About this task

For example, suppose that your report displays these anomalies:

  • Anomaly A: -1.44
  • Anomaly B: 0.32
  • Anomaly C: 0.85

If you configure the report to display the top two anomalies, then the report displays Anomaly A and Anomaly C. Since the absolute value of Anomaly B is the least, it is dropped from the report.

Using this option, you can display the most active anomalies in a report.

Procedure

  1. In the toolbar, click the Options button.
  2. In the Options window, click the Display Top N Values by Std Dev Count checkbox.
  3. In the text box, enter a value for the number of most volatile anomaly detections to display in the report.
  4. Click Apply. The report is updated to display only the Top N anomalies that you configured.
