platforms, written in C) and the Zabbix agent 2 (extra-flexible, easily extendable with plugins, written in Go). Data flow In addition it is important to take a step back and have a look at the overall data flow the configuration file without restarting the agent. To do so, run the new userparameter_reload runtime control option, e. g.: zabbix_agentd -R userparameter_reload or zabbix_agent2 -R userparameter_reload pollers load. Runtime command transfer Zabbix server and proxy runtime commands are now sent via socket instead of Unix signals. This change allowed to improve user experience working with runtime control
