Thank you for your feedback
This provides an overview of all available devices (Search is available). Users can connect to managed devices and review current device status. User permissions and the current state of Nodegrid Cluster nodes determine which devices are displayed.
Device Sessions
When a user logs into the WebUI, the first page is the Access section. This is an overview of all available user-accessible targets. Each device current connection status and available connection types are shown.

In-Use | Blue |
