Viewing logs saved to memory

If the FortiGate unit is configured to save log messages in system memory, you can use the web-based manager to view, search, and clear the log messages. This section describes:

•Viewing logs

•Searching logs

Viewing logs

Log messages are listed with the most recent message at the top.

To view log messages saved in system memory
