Technical Tip: How to disable UUID logging on FortiGate to save storage space

Description

This article explains how to disable UUID logging on FortiGate to reduce log size, minimize unnecessary log data, and help save storage space.

Scope

FortiGate.

Solution

In FortiGate, a UUID is a unique and consistent identifier assigned to policies and objects. It helps Fortinet products track them even if details such as the name, order, or configuration are changed.

UUIDs are mainly used for logging, management, and troubleshooting. They allow FortiGate to add matching source, destination, and policy UUIDs to traffic logs.

This can increase log size and consume additional storage space, UUID logging can be disabled when it is not required.

To disable UUID:

From the GUI:

Go to Log Settings and, under UUIDs in Traffic Log, disable 'Policy and/or Address' and select 'Apply'.

From the CLI:

config system global
    set log-uuid-address disable
    set log-uuid-policy disable
end
