Nagios Support Forum

I am seeing a lot of the following warnings when doing pre-flight checks.
The host template has matching check and notification intervals. Also tried to test by changing the service templates with matching intervals but doesn't seem to matter.

So will this impact anything if ignored. As we put more servers, this warning will become bigger and bigger, since it is warning about every service.

Warnings will never cause the nagios process to fail, only Errors will. This specific Warning is saying, basically, "If you have a notification interval of 15, and a check_interval of 30, the notifications will go out every 30 minutes".

Thanks. Good to know. if we have service checks of 24x7 and notifications of 9x5, this would be an expected behavior and safe to ignore.

Actually, notification/check periods are very different from notification/check intervals. An interval says how often something happens, whereas a period says what times it is allowed to happen. The warning you received is related to the interval.
