3. On the Automatic Group Filters page, double-click the value in the Aggregated column.  
   Aggregated groups apply only to automated alert groups. When the Aggregated option appears, it is automatically activated for an automated alert group.  
   Note:  
   If the value of the Automated field changes, the value of the Aggregated field also changes. You can change the value of the Aggregated field only if the value of the Automated field is true.
4. Select true for the specified filter to apply to groups with identical CIs and pattern identifiers or select false to ignore the filter and create aggregated groups for all alerts in the system.

By configuring these attributes as pattern identifiers, you can control which characteristics are used to group alerts. This customization creates meaningful alert groups, improving alert management and response times by reducing noise and enabling focus on critical issues.")
