Hi Bartosz,
As for me - zabbix is bad practice to place on controller nodes when large
installations will be monitoring, cause it can slow down disk IO on big db.
If it happen - controllers can became unresponsible to other services on
controllers. Zabbix guys recommended to use separate station for large
installations.
But zabbix in HA on dedicated nodes (not on the controllers) is very good
idea to eliminate monitoring SPOF.
