Nagios Support Forum

Looking for an updated recommendation on specs for our XI server. I've referenced this doc already: https://support.nagios.com/kb/article.p ... ategory=83 but that one only goes up to 500 hosts and 2500 services so I'm looking for some info on bigger deployments. Currently this is what our environment looks like and i'm wondering if/when I should be looking to increase anything:

CentOS 6.9
XI 5.4.8
1,219 Hosts
13,299 Services
8 CPU cores
16 GB RAM
Ramdisk implemented
rrdcache enabled

I'm mostly looking for info one when I should be looking at increasing CPU and RAM. Currently averaging about 50% CPU usage, about 3 on the CPU load check, and I'd say between 10 and 14 GB RAM usage. If you need more info let me know. We're not experiencing any issues currently, this is mostly just looking to stay ahead of any upgrade needs.

CentOS 6.9
XI 5.4.10
1231 hosts
25173 services
6 CPU cores
32 GB RAM
Ramdisk implemented
rrdcache enabled
1 mod gearman server for all mrtg checks

Everything works stable, except reporting takes a very long time to complete and is more or less unusable. Also several visualisations are unusable due to too many objects. (eg hypermap). Loading host and service groups takes a long time, but I have a lot (226) of hostgroups..

Apply Configuration takes some time too. Certainly the afterlag (hosts in downtime popup in open service problems) is a bit annoying. I've seen people on this forum with much larger setups.

Grtz

Thanks @WillemDH!

@snapon_admin, Does this set up give you some more insight?

The article is a general example of what you would expect to have. With many different environments out there, there isn't a real answer.

It depends on the type of checks you run. The article is just the minimum, so depending on your checks you may need more.

Of course with that many hosts/services, I would not use an offloaded DB, since your set up is working just fine.
