Re: [Zabbix-users] millions of agents/hosts to distributed active-active zabbix server with distributed DB

[Evan <eva...@qq...>]

1 million will  be  reached , half of it of course. the  point is single instance  of  zabbix server is neither reliable nor effective. 

a compromise solution as  below :
(groups of agents + 1 zabbix sever(failover) ) * N
deffects:
1.same concern
2.many zabbix server failover clusters to operate

zabbix or its backend db is  not the bottleneck as it's just for alert triggers and metric data kept in 3rd places,with mq located in frontend.

>> Searched but found nothing, proxies(cluster) are just for one central point, for instance for different available zones, to gather metric data delegating Zabbix Server, however on the Zabbix server side, only one instance of Zabbix server(failover or primary-backup mode) I’m afraid it’s not enough for all of them to serve API requests or trigger alerts. So is it possible to have an active-active cluster of Zabbix server, any potential risks/problems exist, just for one purpose - one or more Zabbix Server down then nothing effected but only the performance.
