I am not able to find out any link that displays the benchmarking report for the cores. We have to monitor 50,000 hosts and 30 services per host
- per minute host check : icmp
- per 5 minute service checks : telnet and snmp
We have been using Nagios 3 along with OMD (Check MK) to monitor network of half the size, that is 25,000 hosts and 30 services per host. But now the monitoring infrastructure is coming short on performance and with the new releases in place describing a better scalability we would like to switch on a core that is more scalable in terms of check execution, per cpu core per server.
