On-call group interface overview
The on-call group interface allows users who have the correct permissions to view and edit on-call groups.
You can view the group interface for on-call groups if you have permission to view groups and you have a role that is configured to be an observer of the group. If you are also a Group Admin of the group, you can modify the group including adding and removing members and adjusting the shift schedule.
On-call group interface tabs
The on-call group interface uses four tabs that allow you to configure and manage your on-call group.

The Overview tab provides an at-a-glance summary of your on-call group. It shows details about the Group Admins and Observers, how many members and shifts there are, who is currently on duty and if there are any scheduled temporary replacements, any services owned by the group, and any active incidents they're impacted by.

The Schedule tab allows group admins to view and manage an on-call group's Calendar and Shifts. From here, you can add new shift to the group.
The Calendar section displays a schedule view of an on-call group's shifts for a single day, a week, or an entire month at a time. You can use this view to instantly see how shifts overlap, and if there are any gaps in a schedule that are not covered by a shift.
The Shifts section displays a list of all the shifts for the group, and includes information such as the number of members in each shift and if there is a set rotation. Details of an individual shift can be viewed by clicking the name. The side panel displays the members of each shift, the order that group members are contacted, and the amount of time each member is given to respond to a notification before it escalates to the next member. From here, you can also define a shift rotation so that the group members take turns being the primary on-call responder.

The People tab displays information about the Group Admins, Members, and Observers of the on-call group.
Members
The Members section of the People tab displays the names and shift schedule of all users and groups that are members of the group. If you have appropriate permissions, you can click the name of a member to view more detailed information about them. When you click the name of a user, xMatters displays their user contact card with device details and group membership information. Clicking on an broadcast group name displays the name and description of the group, clicking on an on-call group displays a 'Who Is On Call' dialog box with a summary of the group's current on-call shifts, members, and escalations.
The Shifts column displays the shifts schedule for each group member. From here you can verify that each group member has been assigned to the correct shifts and adjust their assigned shifts if necessary. The Roster view also allows you to add new members to the group and assign them directly to shifts. When you assign a user to a shift they are added to the end of the escalation timeline. You can adjust the shift escalation timeline from the Shifts tab.
Group Admins
The Group Admins section of the People tab displays the name, site status, and last login information of all users that are admins of the group. Click the name of a group admin to view the user ID, site, time zone, devices, and other groups they are part of. To manage their devices, click Edit Devices to view the Devices tab of their user profile.
Observers
Observers are roles who can see this group when searching for recipients and target it for notification. The Observers section of the People tab displays the names of the roles that are observers of the group. By default, the group is observed by all roles.
Group options
You can update the group's details, status, notification settings, duplication settings, holiday calendar, time zone, or add a shift from any tab in the on-call group interface.
