Viewing system resources information

On the Status page, you can view the CPU, memory and hard disk usage information and the session information.

By selecting the History link under System Resources, you can also view the statistics for the previous minute.

If CPU and memory use is low, the FortiLog unit is able to process much more traffic than is currently running. If CPU and memory use is high, the FortiLog unit is performing near its full capacity. Putting additional demands on the system might cause log message processing delays.

Changing the firmware

Use the following procedure to upgrade the FortiLog unit to a newer firmware version or revert to a previous firmware version.

If you are reverting to a previous firmware version, the procedure reverts the FortiLog unit to its factory default configuration and deletes all configuration on the unit. When you upgrade the firmware, the FortiLog unit maintains the configurations you define.

Back up the FortiLog unit configuration before beginning this procedure. For information, see “Backing up system settings” on page 39.

Note: If you revert to a previous firmware version, because the configuration is reset, you will need to reconfigure the IP address from the front panel of the FortiLog-100 and FortiLog-400, and the console for the FortiLog-800.
