What command is used to monitor the log rate coming from each device?

The command used to monitor the log rate coming from each device is "Diagnose log device." This command is essential for network administrators who need to assess the performance and behavior of devices in their security infrastructure. By executing this command, you can gather valuable information about how frequently logs are being generated by each device, which can help identify any anomalies or changes in logging behavior over time.

Monitoring the log rate is crucial for maintaining the efficiency of the logging system, ensuring that there is no bottleneck or overflow that could lead to missed events or alerts. This level of monitoring can also assist in understanding trends in network activity and fine-tuning the logging settings for optimal performance.

While other options may refer to related tasks, they do not specifically provide the mechanism to directly monitor the log rate from devices. For instance, "Monitor log-device rate" might suggest an activity related to monitoring, but does not represent a valid command within Fortinet's command structure. Similarly, options that focus on inspecting device logs or showing log rates without the specific diagnostic context do not fulfill the requirement as effectively as the correct command does.
