Maximum number of Hosts Zabbix 1.7 can monitor

[morgolis]

Hello Alexi,
My current employer is looking to replace Nagios and use Zabbix, however, we have nearly 1000 hosts to monitor which are nearly all Solaris / Linux servers. Can you tell me what the maximum number of hosts that Zabbix can currently support?

Thanks.

The specs allow for an unlimited number of monitored hosts and items. If your diskspace and database server allow it, you'll manage. I do think you might run into trouble if you have many items you poll quite often. You migh consider upsing more suckerd processes in that case.

Can you tell me what the maximum number of hosts that Zabbix can currently support?ZABBIX has no limits. However, hardware requirements obviously depends on number of checks per second. If you want to monitor one metric per each server per minute, a Pentium class server may handle it. If each server has, say, 20 metrics, I would go for a P4 3GHz with fast disk I/O.

ZABBIX v1.1 will hopefully introduce active agent checks, i.e. no polling, ZABBIX agent itself will send required data to the server. This should significantly decrease hardware requirements of the server.

Hmm, this will impact firewall rules... Is this going to be the new default or will it be an option?

The way it works now also effects firewall rules.
And - at least it has to, if there is a firewall between server and client.
