Fortigate not showing Deny logs

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.

Run the debug flow commands to see whether your denied traffic is hitting a firewall policy with a log setting enabled.

If the destination is the wan IP interface and not a VIP/port forward, try looking under Local Traffic.

Agree. So @Sozo_Admin , what is your interesting traffic?  Is it a passthrough traffic or terminated on FGT?

Jerry
