Setting Anomaly Alert Conditions

The following Alert conditions can be set:

Influencing metrics
Metric Values
Maximum/Minimum metrics in an anomaly

Before setting Alert conditions, you must set an Anomaly alert. See Setting Alert Types.

Important For an alert to be triggered, all the settings and conditions must be met. 

INFLUENCING METRICS

An alert is triggered only when the conditioning metrics meet the additional specified conditions. 

  1. Set an Anomaly alert.
  2. Scroll down to Conditions.
  3. Click the Conditions Conditions_Icon.ico icon.
  4. Select Influencing Metrics.
  5. Set the Influencing Metrics by selecting the metrics to which the conditions will be applied.
    a/  Click the Set button, to display the Set Influencing Metrics dialog box.
    b/ Define a metric, the  same way you would in any Metrics expression
    Note: There  is no limit to the number of metrics but the 'what' of the metric must be a single 'what'; for example anomalies_simulation_hit_rate. 
  6. In Choose Matching Properties
    a/ Open the Matching Properties drop-down menu. The menu displays the properties shared by the Influencing metrics and the Alert metrics.
    b/ From Matching Properties menu, select one or more properties which are common to both the  Influencing metrics and the Alert metrics.
  7. In Select Time Scale, select
    a/ The time span which the metrics will be aggregated [1 min/ 5 min/ 1 hr /1 day /1 week].
    b/ Whether to use the values Before or During the anomaly.
  8. In Set Conditions, set conditions on the conditioning metric values. The conditions can be either one or all of the following conditions:
    a/ Above or equal to a value you set
    b/ Below or equal to a value you set
    c/ Between two values you set

Note: To help you keep track of the conditions you've set, the auto-fill condition statement at the top of the Influencing metrics panel is completed. An alert is triggered only when the conditioning metrics meet all the conditions.

METRIC VALUES

  1. Set an Anomaly alert.
  2. Scroll down to Conditions.
  3. Click the Conditions Conditions_Icon.ico icon.
  4. Select Metric values.
  5. Set Metric Values for:
  • Alert on an anomaly with direction Up if the metric value is larger or equal to the set value
  • Alert on an anomaly with direction Down if the metric value is lower or equal to the set value

MAXIMUM/MINIMUM METRICS IN AN ANOMALY

  1. Set an Anomaly alert.
  2. Scroll down to Conditions.
  3. Click the Conditions Conditions_Icon.ico icon.
  4. Select if you want to set Maximum Metrics in an Anomaly, Minimum Metrics in an Anomaly or both.
  5. a/ Select Maximum metrics in an anomaly to trigger the alert if there is a maximum number of metrics in an anomaly
    b/ Select Minimum metrics in an anomaly to trigger the alert if there is a minimum number of metrics  in an anomaly
    Note: You can set the maximum or minimum either as absolute values or percentages or both.

When you have completed setting and defining the alert and conditions, click Save, to return to the Edit Alert window.
