1. Check Your Filters
Is there a chance that the filter you are using is not matching any data? For example, this filter will never match any data:
User 'Equal to' John
User 'Equal to' Sarah
Instead you should use this:
User 'Equal to' John, Sarah
(treated as John OR Sarah)
This filter will also never match:
Site 'Equal to' youtube.com
as 'Site' expects a sub-domain such as www.youtube.com.
Instead you should use:
Site Domain 'Equal to' youtube.com
Site 'Contains' youtube.com
Also be careful of the dreaded typo:
Site Domain 'Equal to' yuotube.com
For more information on reporting on sites, please see Reporting on Websites with Fastvue Reporter
2. Reporting on older Dates
Another reason for blank reports is if you're reporting on a date range that has been purged from Fastvue Reporter due to the retention policy in Settings | Data Storage | Settings (default is 90 days of 50 GB, whichever comes first).
To check, go Settings | Data Storage to see what dates you actually have available to report on.
3. Unauthenticated Users
Fastvue Reporter integrates with Active Directory to match user objects in AD with authenticated usernames in the web filter log data.
If you select a user that has not created any authenticated traffic through the ContentKeeper device, the report will come back blank. The same is true when reporting on other Active Directory objects that cannot be matched to authenticated usernames in the log data (such as Departments and Security Groups).
To check, run an unfiltered Overview Report and go to the Top Users sections of the report. If you only see IP addresses, then no users are authenticating.
If you know the user's IP address, you can run a report on Source IP 'Equal to' <IP Address> instead. Likewise, you can run reports on Subnets by selecting Source IP 'In Subnet' 192.168.1.0/24 (replace with desired subnet).
Otherwise, ensure your users are authenticating with ContentKeeper for all their web browsing activity, to ensure their activity is logged and reported on appropriately.
