It'd be nice to set up alerts for unresponsive agents in our dashboard so that after a certain amount of time passes we are notified to check. In most cases, it's likely devices will just be offline, but it'd be good to have a way to uncover if the device is online and just not communicating for some reason. Likely an alert that would be greater than 2 days (don't want a laundry list of alerts after every weekend passes).
