Debug
The Debug configuration provides advanced diagnostic tools to assist in troubleshooting and system analysis. Use the Save Debug File feature to generate a comprehensive archive containing configuration files, system logs, and operational telemetry. The appliance can store a maximum of three debug files locally. You can download these archives to your management computer or upload them to a remote FTP server for further analysis by Fortinet Technical Support.
A critical component of the system debug file is the crash log. Because downloading the full crash log can significantly impact browser memory performance, the system allows you to download a lightweight text file containing only the crash log filenames. This alternative provides a summary of available diagnostic data without the overhead of the complete log files.
