You might come across an instance where your Reports menu is missing from within the FortiGate GUI. I noticed this today when I went to disable local report emails and wasn’t able to!
We use FortiAnalyzer for our reports, so when transferring to this we disabled Local Disk logging, this in turn removed the reports menu.
It is a quick fix to get the menu back;
Connect to your FortiGate GUI
Log & Report > Log Config > Log Settings
Enable Disk logging
Enable Local Reports
Log out and then Log back in, you will now see the menu
Log & Report > Log Config > Report
In my case we disabled “Email Generated Reports” and then disabled Local Reports and Disk logging. By disabling Local Reports you clear the FortiAnalyzer message you might have come across earlier.
