What type of information can you gather with the command 'Diagnose test application oftpd 3'?

The command 'Diagnose test application oftpd 3' is utilized primarily for monitoring and gathering information about the operations of the FortiAnalyzer, specifically in relation to the OFTP (Optimized File Transfer Protocol) service. When executed, this command provides insights into the devices and IP addresses that are currently connecting to the FortiAnalyzer.

This capability is essential for administrators to understand which endpoints are interacting with the FortiAnalyzer, thus enabling better visibility into network activity. This includes monitoring new connections, checking for unexpected devices, or validating that intended devices are successfully communicating with the FortiAnalyzer.

In contrast, the other options involve different aspects of FortiAnalyzer functionality. Network traffic usage focuses on bandwidth and flow statistics rather than connection information. Logs received would pertain to event and incident records rather than real-time connection details. Performance analytics typically relates to the analysis of system performance rather than the identification of connected devices. Therefore, the focus of the command aligns specifically with identifying devices and IPs connecting to the FortiAnalyzer, making it the accurate answer.
