Chrome ‘Device Usage’ Alerts in GAT Shield

Do you want to track down a missing device? Do you know the serial number? Or know the last person using it? If yes, you can use GAT Shield Device Usage alert to get notified.

How to Configure this Alert.

1.Launch the GAT Shield tool.

2.Enter the Alert Rules section.

3.Select Device Usage from the ‘Add a rule’ drop-down menu.

4.Give the rule a meaningful name. Check the box to activate the rule. Now, enter the user’s email address and/or serial number. If both are entered one of them will take precedence if detected first when the rule is triggered on the device.

5.Check the box Report Screen Capture to take a screenshot of the page they were browsing at the time the rule is fired.

6.Optionally you can take a webcam picture of the person behind the device.

7.There is an option to display a message to the user if you turn ON End user action.

Once the alert is triggered an email is sent to the G Suite Super Admin.

When GAT  Shield receives a signal that the device is active, the admin will receive an email with a screenshot of the page opened, and location on a map where the device is located.
The Device Usage rule will be switched to disabled once the rule is fired to prevent getting multiple alerts for the same user or device.

Calendar Event Reporting

GAT+ lets Admins run scheduled reports to show the amount of time each user has allocated to events marked in their calendar.

GAT Scheduled Reports Button

First from the GAT+ home page, under ‘Reports’, select ‘Scheduled Reports’

Next select Calendar Events Stats and the press ‘New report’

Once in the new report, configure as to best suit your needs.

You can give the output report a name of your choice, if not it will default to ‘Calendar Events Stats’ and a date combination.

You can also ask the scheduler to look back a number of weeks and then select to run ‘Just Once’. This will generate a one time historical report.

You can also make other selections such as looking back 1 week and then running the report every Monday to cover the previous week.

The report output will measure event durations in minutes for each user.

GAT Shield Personal – Configuration

GAT for Chrome allows users to configure sup-pages. Here you can configure a page beneath a site and GAT will then monitor activity not just on the site, but also on that specific page. An example is preloaded for you to show how to track visits to the GAT Tech-Tips page for its Google Apps Audit Tool.

Here’s the link.

GAT configuration

You only have to fill out two of the fields, the domain and the subpage. From the URL the domain field is and from the sub-page the field is help-docs. The ‘Name field is optional. If it is not filled in, the URL will be used in the reports. Sometimes the URL can be very long and not so clear, so it is nice to have the option to give it a meaningful name.

In the screenshot above we also see some examples of tracking usage of specific Google tools.  For example, if you want to know how long you spend each day building Google Slide presentations, take the first part of the Google Apps slide tool URL –

The Domain is

The Subpage is /a/

(because here the example domain is – for this part you should see your own domain name). And finally, we give the rule it’s own name ‘Presentations’.  


This will appear in the Browsing Activity Visualization like

To remove a rule just click the rubbish bin beside it in Special Cases table. 

GAT Shield Personal – Browsing Activity

GAT for Chrome can present your entire day’s activity in a number of different ways.  When you start GAT for Chrome you are taken immediately to the Browsing Activity page, which in turn has two sub-pages, Overview and Full Data.


The Overview tab is open by default and it contains a wealth of information. The first section shows your cumulative time on this chrome browser today, each page you visit is brought together to give you a solid bar showing when and for how long you spent your time on each site.

Beneath that each section shows in order of time spent, the list of individual sites you visited and the time spent on each one along with a visual indication of the time of the visit(s).

The number of site visit timetables displayed can be selected, the default is 5. These sites can be listed in reverse order to show least visited first.

Individual sites can be searched for, and previous days can also be selected.


Full Data

The ‘Full Data’ tab shows the entire collection of site visits shown as a pie chart. Mousing over any segment shows you what the site or page being represented is.

Sites that are searched for are automatically brought to the top of the pie chart. In the above example, it is easy to see that nearly 75% of the online day is spent on just 4 sites or pages.

See the Config help page to find out how you can track usage of an individual page within a site.
