Re: High memory utilization on Fortigate 80E
There is no way to list the most-used IPS signatures.
But, it's not so much the signatures in use but the signatures the FGT has to check...if you enable all available signatures the FGT will really have to work a lot. And IPS is memory-intensive.
create UTM profiles for different user / host groups (clients, servers, guest WiFi). Select IPS signatures according to the threats you expect for each group. For instance, you will not check Linux signatures if all of your hosts run Windows...
