Overview

The Overview section provides an interactive, visual summary of update rollout status across deployment rings. It uses ring-based pie charts to help administrators quickly assess update adoption and device coverage. By default, up to five charts can be displayed at a time. Administrators can use the chart filter to select or deselect rings as needed. If custom rings are configured, one of the existing charts must be deselected to display the custom ring chart.

Default Ring Charts

The following charts are available by default:

• Canary Ring: Displays devices that receive updates immediately on release day with no deferral. This ring is typically used for early validation and testing.
• Early Adopters Ring: Displays devices that receive updates after a 3-day deferral period, allowing limited rollout after initial validation.
• Broad Rollout Ring: Displays devices that receive updates after a 7-day deferral period, enabling wider deployment once updates are deemed stable.
• General Availability Ring: Displays devices that receive updates after a 14-day deferral period, representing full-scale deployment across the organization.
• Devices With No Ring Assigned: Displays all devices that are not currently assigned to any update ring, or whose ring assignment is pending or has failed. Unlike other charts, this chart reflects ring assignment status rather than update installation status.

Chart Status and Update Lifecycle

All default and custom ring charts display device update status using the following states:

• Installed – Devices where the update was successfully installed.
• Scheduled – Devices that are assigned the update but for which the update process has not yet started.
• Download In-Progress – Devices that are currently downloading the update package.
• Prepared for Installation – Devices where the update has been downloaded and prepared and is ready for installation.
• Install In-Progress – Devices that are currently installing the update.
• Failed – Devices where the update installation failed.

The Devices With No Ring Assigned chart uses a different set of status values to reflect ring assignment state:

• Not Assigned – Devices that are not associated with any update ring.
• Pending – Devices for which ring assignment is in progress..

Update Flow Across Rings

When devices are assigned to the Canary Ring and a new iOS update becomes available for the selected month:

• Devices transition to the Scheduled state when they are assigned an update but the update process has not yet started.
• As the update deployment progresses, devices move through the following states based on their update status:
  • Download In-Progress – The update package is being downloaded to the device.
  • Prepared for Installation – The update has been downloaded and prepared for installation.
  • Install In-Progress – The update is currently being installed on the device.
  • Installed – The update has been successfully installed on the device.
  • Failed – The update installation failed.
• The displayed status reflects the current stage of the update lifecycle on each device.

note

For the Early Adopters, Broad Rollout, General Availability, and any custom rings, devices may not immediately appear as Pending even when an iOS update is available. This is expected behavior, as these rings follow their configured deferral periods. Devices in these rings remain in an awaiting scheduled installation state until their deferral window elapses.

Devices With No Ring Assigned

The Devices With No Ring Assigned chart provides administrators with a consolidated, high-level view of devices that are not part of any update strategy. The Not Assigned status highlights devices that have no ring configuration applied, enabling administrators to quickly identify unmanaged or overlooked endpoints and take corrective action.

Interactive Chart Behavior

All charts in the Overview section are interactive. Clicking on any chart against any category (Installed, Pending, Failed) opens a detailed view that displays a device-level table with the following columns:

• Device Name
• Device Model
• Device Group
• Status (status of the ring)

The table also provides the following controls:

• Month Filter Dropdown – Allows selection from the latest three months of iOS update releases (Filter affects all the default and custom charts except Device with No Ring Assigned)
• Search – Enables quick filtering of devices by keyword
• Refresh – Reloads the latest device and update status

note
The Devices With No Ring Assigned chart does not include the month filter dropdown, as it represents ring assignment state rather than update release data.
