Recording logs Logging and reporting

Recording logs in system memory

If your FortiGate unit does not contain a hard disk, you can configure the FortiGate

unit to reserve some system memory for storing current event, attack, antivirus, web

filter, and email filter log messages. Logging to memory allows quick access to only

the most recent log entries. The FortiGate unit can store a limited number of

messages in system memory. After all available memory is used, the FortiGate unit

deletes the oldest messages. If the FortiGate unit restarts, the log entries are lost.

To record logs in system memory

1 Go to Log&Report > Log Setting.

2 Select the Log to memory check box.

3 Select the severity level for which you want to record log messages.

The FortiGate logs all levels of severity down to, but not lower than, the level you

choose. For example, if you want to record emergency, alert, critical, and error

messages, select Error.

See “Log message levels” on page 312.

4 Select Config Policy.

To configure the FortiGate to filter the types of logs and events to record, use the

procedures in “Filtering log messages” on page 313.

5 Select Apply.
