Further clarification - yes, the hub PC will indeed display the alert for a status change reported to the hub for a monitored PC. If the hub and the monitored PC are online within the LAN, the alert will appear immediately, when that status changes - green to yellow or red, or red or yellow back to green. If the hub is powered off, the alerts will appear as soon as it connects if the monitored PC is on. If the monitored PC is off, when it connects (user logs in) the alert will appear on the hub.
