What is the purpose of the diagnose log device?

The diagnose log device is primarily used to display disk log usage and allocation. This functionality is crucial for administrators as it provides insights into how much of the disk space is being utilized for logging purposes, helping them manage log storage effectively. Understanding disk log usage is essential for maintaining optimal performance and ensuring that the logging capacity does not reach its limit, which could lead to loss of important log data. This tool allows administrators to efficiently monitor and allocate disk space, ensuring that the system continues to function without interruption.

While options related to active user sessions, network traffic monitoring, and configuring firewall policies are important aspects of network management, they fall outside the scope of what the diagnose log device is specifically designed to handle. The focus on disk log usage and allocation highlights its specialized function in log management within FortiAnalyzer.
