Is it possible to allocate memory space for each log category in a Fortigate?

[jefazo92]

Hi everyone,

I want to allocate X, Y, etc. amounts of memory to storing certain log categories. Is it possible to do this in a Fortigate 100F?

Hi @jefazo92 ,

As far as I know, You can specify how much memory space the logs will take globally, but not by categories.

Thank you very much @ozkanaltas. Do you know how may I find the current (default) value assigned for memory logging? Is there a command which shows the current set value for

Hello @jefazo92 ,

You can see the default value with these commands. 

config log memory global-setting
show full-configuration

 Category-based memory allocation is not possible in Fortigate. However, you can optimize the memory usage by tweaking the  following settings 

config log memory global-setting
set max-size 19568107
set full-first-warning-threshold 75
set full-second-warning-threshold 90
set full-final-warning-threshold 95
end

config log memory filter
set severity information  <--- you can change it warning 
set forward-traffic enable
set local-traffic enable
set multicast-traffic enable
set sniffer-traffic enable
set ztna-traffic enable
set anomaly enable
set voip enable
set forti-switch enable
end
