Howdy all,
I am trying to view Deny traffic logs on a Fortigate 30E
(FortiGate 30Ev6.2.15 build1378 (GA)
and they are not showing up.
Via the CLI - log severity level set to Warning
Local logging
Here is the details:
CMB-FL01 # show full-configuration log memory filter
config log memory filter
set severity warning
set forward-traffic enable
set local-traffic enable
set multicast-traffic enable
set sniffer-traffic enable
set anomaly enable
set voip enable
set filter ‘’
set filter-type include
The Fortigate is getting hammered, with alerts coming in thusly: (Sanitized)
Message meets Alert condition

Implicit Deny policy in place - set to log violation Traffic:
However I can find no deny logs:
Nor can I see the Implicit Deny object when trying to search logs by Policy:
I don’t know if I am missing something obvious, or have configured something incorrectly.
If anyone has any advice it would be appreciated!
Thanks to any takers.

Hi @Sozo_Admin ,
What I meant is that due to limited memory, the new logs will overwrite the old logs when there is not enough memory to save all the logs.
Howdy funkylicious,
Destination is LAN, sorry but thanks!
Hello @Sozo_Admin,
Can you please review the below document and confirm that you have all the needed settings enabled on the firewall for implicit deny logs?

Hello Sozo_Admin
Ensure logging on the implicit deny is enabled.
See the following article: https://community.fortinet.com/t5/FortiGate/Technical-Tip-Implicit-deny-logs/ta-p/194602
