Which command retrieves the message receive rate for each second?

The command "Diagnose fortilogd msgrate" is specifically designed to retrieve the message receive rate, displaying how many log messages are processed by the system per second. This command is useful for monitoring the performance and efficiency of log processing in FortiAnalyzer.

By issuing this command, the user can assess whether the log collection mechanism is functioning optimally or if there are any potential bottlenecks in receiving log messages. It provides real-time data, which is essential for troubleshooting and ensuring that the logging infrastructure can handle the incoming traffic without losing messages.

The other choices do not serve this specific purpose. For example, the command related to debugging generally enables or disables debugging features and does not pertain to log message rates, while the log device command focuses more on the configuration and status of log devices rather than real-time message rate statistics.
