We are currently working towards migrating from Nagios 2.7 to 3.2. We have 37,000+ services and 3,000+ hosts. We have a test environment with an 8 CPU system running Nagios 3.2.1 and we are getting high latency of 330+ seconds. The configuration has the large installation tweaks turned on and max_concurrent_checks=10000000. The load average on the system is around 3 to 4, but the CPU utilization is less then 50% on the average, with peaks of 80+% that might last 1 second about every 10 or 15 seconds.
So my question is this - Is there something that we can do to lower the latency and increase the CPU utilization? Is there some limiting factor with our configuration that we need to tweak, or is it just too many checks for the main Nagios process to handle in the time frame, or something else? I can provide any information that would make it possible to lower the latency. Thanks!!
