It would be nice to have that widget or report to know the number of devices that has not checked in or last scanned. I think having this will improve the accuracy of the rest of the reporting. All the reports are based on the devices that are online but it does not account if the device's agent is not functional. Then, the reports are not showing the correct data. When you see devices that are non-compliant, it is more than likely the agent is not operational.
