To configure grouping of events in the Incident manager, do the following:

1. Go to the settings panel of the Incident manager object and select the Group by tab.
   
2. In the Group by drop-down list (1), select the event grouping option for the Incident manager interface:
   1. Operator — the operator can choose the grouping method in the Incident manager interface.
   2. Disabled — the event grouping is disabled.
   3. Region — the events are grouped by region.
   4. Event — the events are grouped by event type.
   5. Object — the events are grouped by object.
3. Set the Process whole group checkbox (2), which sets two options: 

   1. in case one operator takes an event from a selected group for processing, all events of this group will be blocked for processing by other operators. When the checkbox is set, all events of the selected group, including new incoming events, will be available for processing by only one operator until he finishes processing all the events of the group. Other operators will not be able to take events from this group for processing — when they try to do that, the warning message "Group is blocked" will be displayed.

      If the operator took one event from the group for processing and released it without processing, then the events blocked by the group become released for other operators.

      
      

   2. when one event of the selected group is escalated, all events of this group will be escalated too.
4. From the Grouping in list drop-down list (3), select the event grouping option:
   1. no grouping — all events will be displayed in the event display window without grouping. If filtering is set, then all events of the selected filter will be displayed.
   2. by event — the events will be grouped by object type / object ID / event type / logic ID.
5. Set the Show only first event in the group. Close others without processing checkbox (4), it is necessary to show only the first event from the group and close the rest of the events without processing after the first event is processed.
6. Click the Apply button.
