To add a title to the report, enter the title in the text box.
Report Mode
Select a mode for the report.
Display Top N Values by Std Dev Count
When selected, you can configure the report to display the topmost anomalies that you specify in the checkbox. Additional information on Top N filtering is available in the Info tooltip.

Report Mode

As needed, you can configure the report to be displayed in one of the following modes:

Mode
Description
Custom
Anomaly Detections included in the report are displayed according to your specific selections.
All Hourly Anomaly Detections
Anomaly Detection report displays all currently active hourly Anomaly Detections.
Note: Depending on the number of hourly Anomaly Detections currently active in the system, this option can make the chart display hard to read. You must combine this mode with a Top-N configuration to limit the display to the most active Anomaly Detections.
All Daily Anomaly Detections
Anomaly Detection report displays all currently active daily Anomaly Detections.
Note: Depending on the number of hourly Anomaly Detections currently active in the system, this option can make the chart display hard to read. You must combine this mode with a Top-N configuration to limit the display to the most active Anomaly Detections.

As needed, you can configure the automatic creation of hourly and daily Anomaly Detections for events and dimensions.

Visual Threshold

For a configured report, you can define thresholds at which to apply visual shading to the display to indicate that the shaded areas are not important to the report.

  • In the Options screen, click theVisual Threshold check box to enable thresholding.
Option
Description
Threshold
Set this value to a positive number to indicate the absolute value of the threshold to apply to the report. Each integer value for the threshold corresponds to one standard deviation. You can apply one threshold at a time to a report.
Direction
Define the direction to which the threshold is applied:
  • Positive and Negative - Anomalies with standard deviation counts greater than the positive of the Threshold value and less than the negative of the Threshold value are considered to be important. Values inside these threshold limits are shaded.
  • Positive - Anomalies with a standard deviation count greater than the Threshold value are visible. Other values, including negative values, are shaded.
  • Negative - Anomalies with a standard deviation count less than the Threshold value are visible. Other values, including positive values, are shaded.
  • If a positive integer is entered for a negative threshold direction, it is automatically converted to a negative value.

To apply the specified threshold, click Apply.
