The Event Handler feature provides several traffic rules that allow you to automatically perform various actions when data usage exceeds a specified threshold. These traffic rules can be customized to fit a variety of conditions, such as checking the data usage of a single SIM on a daily basis, or checking the total data usage across all SIMs on a monthly basis.

When using a traffic rule with a group, Event Handler previously only supported checking the data usage of each SIM in the group separately. In other words, an Event Handler's actions would be run whenever any individual SIM within the group exceeded the specified threshold.

With this update, you can now also configure an Event Handler rule to check the total daily or monthly data usage across all SIMs that belong to a specific group. Rather than checking each SIM's data usage separately, these new rules will check the total data usage of all SIMs belonging to the group.

To configure an Event Handler that checks the total data usage of all SIMs belonging to a group:

1. Choose the Group target and select the group the Event Handler rule will apply to
2. Select either the Daily total traffic or Monthly total traffic rule, based on whether you want to check the daily or monthly group data usage

Note that if a SIM is removed from a group in the middle of the Event Handler's daily or monthly period, any data usage that occurred prior to removal will still be counted towards that group's total traffic. Similarly, if a SIM is added to a group in the middle of the period, any previous data usage before the change will not be counted.
