Which command displays the processes with the highest resource usage?

The command that displays the processes with the highest resource usage is 'diagnose sys top'. This command provides a real-time overview of active processes, sorted by their resource consumption, allowing you to quickly identify which processes are using the most CPU and memory. This is particularly useful for troubleshooting performance issues, as it enables administrators to monitor the impact of various processes on system resources continuously.

By using this command, users are presented with a similar interface to the top command found in other operating systems, allowing for easy interpretation of resource usage statistics. This clarity and accessibility make it an effective tool for managing system performance.

Other commands might provide useful information about system processes or general statistics, but they do not focus exclusively on the highest resource consumers in a way that 'diagnose sys top' does. This specialized information is crucial for efficient troubleshooting and performance optimization on Fortinet devices.
