What command is used to list error counters related to web filtering?

The command that lists error counters related to web filtering is particularly useful for administrators who need to monitor and troubleshoot web filtering issues. By using "diagnose webfilter fortiguard statistic list," you gain insights into how the web filtering process is functioning, allowing you to view statistics that can highlight any errors that may be affecting the performance or efficacy of the web filtering service. This command provides specific details about the relationship between the FortiGate device and the FortiGuard service that it utilizes for web filtering.

This visibility is crucial for troubleshooting and enhancing web security measures. Monitoring error counters can help identify patterns or recurring issues that may require adjustments in configuration or further investigation into network performance or FortiGuard responses.

Other options, such as configuring the FortiGuard system or retrieving OSPF router information, do not pertain to web filtering error counters and therefore are not applicable for that specific purpose. The command for URL filtering testing is more focused on testing functionalities rather than reporting on error statistics. This underscores the importance of using the correct diagnostic command to gather relevant information for effective management of web filtering services.
