Is it possible for Zabbix to alert the activation of PFSense CARP Failover?
Whenever triggered, Zabbix would notify you that it has changed from Master to Slave.

I found the solution, an user of netgate forum helped me.
JimP said in Can I find out the status of the CARP interface (BACKUP / MASTER) through a command?:
ifconfig -a | grep 'carp:'
This solution looks perfect, I only made one adjustment to get only the MASTER / BACKUP:
UserParameter = pfsense.carp.state, ifconfig -a | grep 'carp:' | cut -d '' -f2 | sed -n 1p
Sed is for taking only one CARP interface, it is very rare for one interface to be BACKUP while the others are MASTER, and vice versa.
PS: I don't know if I should close this post as resolved or how to do it if I should.
