Nagios Support Forum

Hey guys, just a quick question... I tried searching around a bit and didn't seem to find a solid answer. But we're looking at putting up Nagios monitoring for an additional 65,000 devices. I'd say probably 2 to 3 checks per device. What's the current standard on server loads from a software standpoint?

Our VMs are pretty beefy so I don't think hardware will be an issue but we just want to get a feel for how many servers we're going to need to monitor that man devices.

Thoughts?

The general recommendation is 32GB of ram with 4-8 CPU cores. This should be able to sustain 20-30k checks, whether it be 10k hosts + 20k services, or however you'd like to aggregate them. This of course would be with some optimization done, such as an offloaded DB, a ram disk, or gearman. (see this link for more of an explanation - https://support.nagios.com/kb/article.php?id=503)

The main limitation gets down to the reporting, where SQL just can't keep up with processing a lot of data.

Thanks for the reply, I'll let my boss know and we'll be contacting sales for more licenses soon O.o

There's more issues than just MySQL, but https://www.mysql.com/products/enterprise/database/ is something to look forward to in the future.

Did you need any help with any of the performance suggestions? If not, are we ready to close this thread?

Sure you can close, appreciate it.
