GAT Shield has introduced two asked for features in Shield version 3.0.3 and up. The first is ‘Other Users’. This is a list of other accounts using the Chrome device at the same time as the logged in user for your domain. The list of users, using other accounts can be filtered using the filter ‘Other Users – is not null’.
The second feature is ‘Estimated uptime’, which in fact measures the uptime of GAT Shield extensions, but if the Shield extension is a forced install on Chrome then it measures the uptime of Chrome. This can also be used to check if forced reboots were successful. It is measured in seconds. If you had a forced reboot 7 days ago and using the filter ‘Estimated uptime is greater than’ 604,800 seconds then the forced reboot has not impacted on this Chrome device.
