You can select to monitor specific users (normally executives) to analyze the amount of time a device has not synchronized with the server. The monitoring of mobile users coincides with alerts. If you are setup to receive alerts for mobile users then you will receive an alert for each key user that has not synchronized in X amount of minutes (the default is 20 minutes).

Go to Servers & Devices -> Mobile Users
Under All Devices, right click on the user you wish to monitor
Enter the duration in which you want to monitor that the device has not synched
Click Apply
The users/devices displayed under Critical Devices are the devices currently being monitored for alerting
To receive alerts for mobile users, select Mobile Users for the alerting event (see section 2.4)
