Virtual IP and Zabbix replica?

Question

Zabbix

Good morning,

Tell me about zabbix.

1. Now the test version of zabbix is ​​running. DB on postgres, everything is on VIP (virtual IP address), because zabbix server 2. The
replicating database works as a master-slave. When the master falls, it switches to the slave. But it doesn't let me go to zabbix.
Is it possible to solve this issue in the database itself by making master-master? Or install the 3rd master server so that there is mms?

2. VIP is made by Ucarp. Everything works, the servers are switched as specified in the config if one of them falls.
But zabbix agent does not send metrics if you specify the VIP address. What needs to be done to make this method work. You specify VIP in the agent - from the VIP the metrics are already transferred to the zabbix server.

Will keepalived help here? Or will it be necessary to enter the addresses of zabbix servers in the zabbix agent?

Thank you.
