Tuning the Alert Rate

For Anomaly and Static type alerts, you can tune the alert settings based on simulation results to meet your alert needs.

Legend

- - - - -   Threshold

______   Alert meets all the conditions set in the alerts settings panel

______   Alert meets some but not all the conditions set in the alerts                            setting panel  

Note

  • If there is no anomaly and the metric value is above or below the defined thresholds, no alert is triggered.
  • To inspect specific trigger values, hover over the metric line. The displayed values depend on the alert type.
  • The total number of Alerts is displayed in the top bar: Estimates Alert Rate. The number of times a specific metric is triggered in the user-defined alert is shown in the metric tile.  
  • Investigate Alert-based anomalies (orange) to determine which settings to adjust to receive fewer alerts.
  • Investigate non-Alert-based anomalies (gray) to determine which settings to adjust to trigger more alerts.

To decrease the estimated alert rate:

  1. In the simulation data chart, trace an alert with the cursor to show the trigger values:
  2. Increase the level of each setting which triggered the alert to decrease the Estimated Alert Rate. Depending on their settings, either one or all of Significance, Delta and Duration may be responsible for alert in above example.
  3. To include anomalies that were not simulated as alerts, decrease the setting levels.
  4. When the simulation Estimated Alert Rate meets your needs, click Save and complete the alert definition.

Note: To display all simulation time periods in the graphs, Anodot down-samples metric data except for periods of anomalies, in which case, the original data points are kept.
