How can you increase the log level using runtime controls in Zabbix?

The method to increase the log level using runtime controls in Zabbix requires sending a specific command to the Zabbix server process. The correct command utilizes a runtime control option that allows administrators to adjust the logging configuration on-the-fly without needing to restart the server.

The command zabbix_server -R log_level_increase effectively instructs the Zabbix server to elevate its log level, which can be essential for troubleshooting and monitoring the server's behavior in real-time. This functionality is particularly useful as it enables administrators to gather more detailed log information when investigating issues.

In contrast, other options do not align with Zabbix's command structure for adjusting logging levels. For example, specifying -R log_level_increase -config does not correctly utilize the runtime control mechanism, as the configuration parameter isn't relevant in this context. Additionally, commands like systemctl increase log level do not pertain to Zabbix's operational controls but rather involve system-level service management, which is outside the specific context of Zabbix's logging control. The option that suggests changing the log level through the command zabbix_server -R change_log_level might seem plausible, yet this is not the correct syntax or command
