I have a Nagios server which monitors many servers.
From time to time we encounter an error which cannot be resolved at the time and we are leaving it for the time being.
When it happens, we keep getting email notifications regarding the failing service.
So if we're not dealing with the problem in the next day - we receive about 500 email notifications regarding it.
Now my question is, what is the difference between notification\_interval and interval\_length and which value should i be editing?
I'm willing to configure it in a way that when an error occurs I will get only 1 notification regarding the issue instead of getting 10 notifications per hour for example.
I want Nagios to send me an email only once when an error occurs and every 12 hours until the error is fixed.
How can it be achieved?
