Hello. We've got a single Nagios server with the following stats 2 x Intel Xeon 2.4Ghz CPUs (hyperthreaded) 3.6Gb of memory Red Hat AS 3 Linux Nagios 2.9 Host Checks: 451 Service Checks: 2358 Average OS load level: 3
Service Check Execution Time (min/max/avg): 0.03 sec 30.04 sec 0.500 sec Service Check Latency (min/max/avg): 0.01 sec 33.67 sec 5.516 sec Host Check Execution Time: 0.00 sec 26.78 sec 0.722 sec Host Check Latency: 0.00 sec 3.68 sec 0.008 sec This box is almost exclusively doing active service checks. It is almost dedicated to Nagios (it does a couple of other things, all very low-volume). This server has grown considerably over time to encompass quite a lot more Nagios activity than it had when I took over Nagios admin. Now it seems active enough to start planning on scaling it somehow. While there will definitely be growth, I'm not really sure how I should break this architecture out. Our Nagios growth is a bit unpredictable as people ask us to monitor their stuff, but I might guess it at 20% per year. I assume I'd want to start looking at the distributed models for Nagios. My problem is that I feel like any architecture I try to plan out is really just a guess for this load (and predicted future load). Can anyone suggest where I should go from here in terms of planning out a Nagios-for-the-future architecture? How many hosts, for example? We looked at possibly going VM with Nagios, but it appears that at least with this configuration, Nagios is taking up too many resources. We could probably scale out with VM's, but I imagine we'd need more VM's (hosts) than we'd need with physical boxes. Any help is greatly appreciated.
