Now that we are familiar both with monitoring using Zabbix agents and an agentless method, let's explore an additional method that does not require Zabbix agent installation, even though it needs an agent of some kind anyway. Simple Network Management Protocol, commonly called SNMP, is a well-established and popular network-monitoring solution. We'll learn to configure and use SNMP with Zabbix, including SNMP polling and trap receiving.
