What does the command "diagnose debug flow show function-name enable" accomplish?

The command "diagnose debug flow show function-name enable" is designed specifically to enhance the output of the debug flow feature by including the names of functions that are being called during the processing of packets. When this option is enabled, it provides deeper insights into the various functions executing in the background, which can be extremely helpful for troubleshooting network issues or understanding how the Fortinet device processes traffic.

This capability allows administrators and engineers to see not just the flow details but also which specific functions are part of that processing, enabling a more granular analysis of the firewall's behavior. This additional context can lead to better-informed decisions and quicker resolutions when addressing network problems or optimizing firewall rules.

It’s important to understand that this feature is part of the debugging tools available on Fortinet devices, which are crucial for operational diagnostics. Hence, enabling function name output provides a more comprehensive view during debugging sessions, making it a vital command for those delving into the intricacies of network traffic handling.
