Nagios Support Forum

Perhaps a warning isn't anything to worry about, but I noticed that when I have:
Which, if I'm not mistaken, says to do a check every 6 hrs unless there's a problem, then check every 30 min. And send notifications only every hour.

Naturally notifications will only send when there's a problem, so they can only send out when it's running at the 30 min check_interval.

If I said everything correctly, then I shouldn't be bothered with this error in the config check:

Warning: Service 'Root Partition' on host 'myhost' has a notification interval less than its check interval! Notifications are only re-sent after checks are made, so the effective notification interval will be that of the check interval.

Or did I do something wrong? I'm pretty new at nagios.

You are 100% correct in what you have said, if memory serves me correctly however once it reaches a hard down state and sends that notification it will resume checking every 6 hours... which means you will get 5 - 6 notifications for it being down even if it recovers in that 6 hour period.

EDIT: I've just noticed you have check_interval and normal_check_interval... I believe both of these directives do the same thing but one of them is deprecated (normal_check_interval I think), you need to use retry_interval instead. I could be wrong but I've never seen them both used in the same config before.
