Zabbix agent is installed on the remote host (target) to monitor the hard drive, memory processor, etc. The agent collects data and sends back to Zabbix Server.
Zabbix agents can use passive or active checks to pass information.
In passive check, Zabbix server (poller) requests an agent for certain information, and the agent sends back a value.
In the active check, the agent process all data and pushes it to the Zabbix server.
However, agent periodically connects the server to collect metric which needs to be monitored.
