What command would you use to debug communication issues between FortiAnalyzer and FortiGate?

The command used to debug communication issues between FortiAnalyzer and FortiGate is "diag debug en." This command enables the diagnostic debug mode on the FortiGate device, allowing for the collection and display of detailed logs that can provide insights into the communication process with FortiAnalyzer. By using this command, network administrators can assess real-time information regarding the interaction between the FortiGate and FortiAnalyzer, which is crucial for identifying any potential issues affecting their communication.

The debug mode offers various specific options to further refine what is being logged, allowing users to track down the root cause of communication problems effectively. This level of detail is essential for troubleshooting scenarios, as it can highlight misconfigurations, connectivity issues, or other anomalies in the traffic flow.

The other options do not provide the necessary detailed logging or debugging capabilities to troubleshoot communication between the two devices. For instance, issuing a logging test, retrieving generic log statistics, or viewing log files would not yield the level of real-time insight required to effectively diagnose and resolve communication issues.
