Zabbix
Hi sirynaine42.
I do not have hard numbers for you, but I've work at two different companies that employed Zabbix. The first one monitored two separate data centers and many branch offices. The second is the company I'm currently with and again its two data centers. In both cases, a separate Zabbix server was used at each data center. Key systems from each data center was (is) monitored from the opposite remote data center.
In neither company's deployment was degradation noted due to Zabbix's monitoring, ping, SNMP or agent. Yes, there are Zabbix agents available.
Both company's had hundreds (>300) of systems being monitored, so I can not confirm the 10,000 ranging of systems.
