Nagios Support Forum

Hello.

I've got a question about the Nagios performance management page here.

There's 2 sections that look contradictory :
Schedule regular host checks
Enable cached host checks

in the first one Schedule regular host checks, it reads :
Scheduling regular checks of hosts can actually help performance in Nagios

In the second one Enable cached host checks, it reads :
on-demand host checks can benefit from caching (...) In order for cached checks to be effective, you need to schedule regular checks of your hosts

It looks a bit contradictory to me. I thought it was either Scheduled hosts check or on-demand host-check, not both at the same time. But here, it says you have to put them together, it's not very clear to me. Can someone please explain ?

Thank you very much.

Your biggest factor for performance is going to be the quantity of checks per second your machine is running. To be honest I'm not sure about the difference with the check scheduling. See my other post with the maximizing performance with XI, even though you're using Core, the concepts for managing check load are still the same:
