Device statuses are displayed on the Devices page and the Device Summary page. An overview of the device statuses of a fleet is shown on the Fleets page. Each device can have one of the following statuses:
|Online||The device is online and is communicating with the cloud within the correct interval. In this state, the device is connected to cloudlink and has had recent API communications.|
|Online (VPN Only)1||The device is online, is connected to cloudlink, but has no recent API communications.|
|Online (Heartbeat Only)2||The device is online, has recent API communications, but is not connected to cloudlink.|
|Offline||The device is offline.|
|Configuring||The device is applying OS configuration.|
|Updating||The device is updating to a new release.|
|Post Provisioning||The device has been provisioned but has not yet come online.|
|Inactive||The device has been deactivated or has been preregistered but has not yet connected to the balenaCloud API.|
|Frozen||The device has been frozen because it's outside the organization's allowance, or is in a paid fleet type on a free tier organization.|
Device Connectivty states
When the device's network connectivity is fully operational, the status displays as Online, which is comprised of healthy Heartbeat and VPN statuses. A device's status may include indicators of partial connectivity issues on the device, such as a firewall blocking VPN traffic or a device's inability to communicate with the balenaCloud API. These indicators are as follows:
Online (VPN Only) indicates that the device is unable to communicate with the balenaCloud API. A device with a VPN Only status is not able to apply any new changes made such as deploying new releases, applying service configuration values, or switching to local mode. However, it is accessible via SSH or the web terminal. Performing an action such as rebooting or restarting containers might work, but most likely will not. This is because the device loses its Heartbeat if it's not communicating with the API, which is usually when the Supervisor on the device is not running or crashing. Since we have VPN access, we can SSH into the device and investigate further.
Online (Heartbeat Only) indicates that device is unable to connect to cloudlink (e.g. a firewall is blocking VPN traffic), and won't be able to provide remote SSH connections. A device with a Heartbeat Only status has internet connectivity and can poll the cloud for new updates to apply. However, performing any actions which do not change the target state or attempting to access the device via SSH will error, as these actions only have effect with a VPN connection. Actions that do not change the target state include purging data, restarting, rebooting, or shutting down, and they all require the VPN because they are proxied from the dashboard API to the Supervisor API on device.
Note: If the device is powered off or loses all network connectivity, it will remain in the
Online (Heartbeat Only) state until the last target state fetch exceeds the device API polling interval.
Debugging Device Status
If you find your device to be displaying a status which is unclear even with the above notes, visit the device debugging masterclass for more information.
