"QuoteAnyway, I see very little about what the Zabbix Agent can do or see, even less on which template I should select. I also see talk about an SNMP template and how OPNsense uses an older SNMPd which may or may not be a problem.
With the agent (and the FreeBSD template), you get similar data as for a basic computer (aka disk-, cpu- and ram-usage, network interfaces and traffic).
