Distributed Setup of Nagios

[Kyle O'Donnell]

we have ~ 30000 services and ~3000 hosts

we have 6 pollers (each have a backup) processing checks and forwarding
back to a central nagios host.

our busiest poller has ~1000 hosts and ~9000 services... avg service check
interval is 5 minutes, but there are a bunch at 1 and 2 minute intervals.

avg service check latency is less than 1 second

This is ~3yr old hardware too, i suspect we could increase capacity by 50%
if we move to the new intel nahalems

we dont use active host checks
