What is the function of the command 'diagnose ha stats'?

The command 'diagnose ha stats' is used in Fortinet's FortiGate to display statistics related to High Availability (HA) operations. When executed, it provides crucial information about the HA cluster, such as the status of cluster members, failover events, and heartbeat timings. This information is vital for network administrators to monitor the health and performance of their HA setup, ensuring that all devices in the cluster are functioning correctly and facilitating seamless failover in the event of a device failure.

Understanding HA statistics is essential for optimizing network reliability and uptime, which is why this command is specifically focused on that aspect of system performance. The other options provided do not align with the purpose of this command, as they pertain to different system functionalities—network status, user logs, and configuration details—rather than HA statistics.
