Activate the predefined alert clustering definitions provided with the Tag-Based Alert Clustering Engine application before use. Utilizing these preconfigured definitions minimizes setup time and ensures a more efficient
configuration process, allowing for quicker implementation and streamlined alert management.

Important:  
If you are already using the Tag-Based Alert Clustering Engine application, all the predefined definitions are inactive and must be activated. In contrast, new customers will find several definitions active by default, allowing for immediate utilization of the alert clustering capabilities without additional setup.
