What does the command 'diagnose ha status' show?

The command 'diagnose ha status' provides detailed information about the High Availability (HA) status of Fortinet devices within a cluster. This command specifically displays the operational status of the HA configuration including roles of the devices (primary and secondary), their health, status of any failover events, and synchronization information. By using this command, administrators can quickly assess how well the HA setup is functioning and whether any issues need to be addressed to maintain reliability and uptime.

In the context of the other options, while the command does touch upon aspects of synchronization and might give insights into logs indirectly, it primarily focuses on the comprehensive HA status which encompasses several critical parameters that inform administrators about the overall state of the HA configuration. Therefore, it distinctly offers HA-specific insights rather than just synchronization status, logs, or performance metrics.
