Notification behavior in Nagios X

Is there an expected behavior diagram for Nagios XI notifications that get sent out?

I recall that in older versions of core that when an item (server or service) is acknowledged (persistent) when it was critical that notifications were not sent out for the service when it became OK. But I'm starting to notice that this behavior is no longer the case when acknowledged with Nagios XI (my installed version Nagios XI 2014R1.5).

Apparently even if a server and services are set into downtime after a service or server was critical, notifications are still received when the state becomes ok even though the server and services are shown as being in downtime. I mean the entire point of scheduling downtime is suppression of notifications. I need to find documentation to explain this to my staff on hand. Or perhaps I've run into a bug?

I found a reference to a notification /escalation writeup here: http://assets.nagios.com/downloads/nagi ... ations.pdf

I found the reference to scheduled downtime here: http://nagios.sourceforge.net/docs/nagi ... ntime.html and the notification options here: http://nagios.sourceforge.net/docs/nagi ... tions.html

These are good places to start. There is a mention of an S option that you can turn off notifications for scheduled downtime - see the forum discussion Re: Scheduled Downtime still sends notifications here: http://support.nagios.com/forum/viewtop ... 367#p94275.

The S option is not checked. Are you saying that by checking the S option that I will NOT receive notifications when in downtime?

Per the Help Documentation, the notification options are described as this:


w = send notifications on a WARNING state,
c = send notifications on a CRITICAL state,
u = send notifications on an UNKNOWN state,
r = send notifications on recoveries (OK state),
f = send notifications when the service starts and stops flapping, and
s = send notifications when scheduled downtime starts and ends.


I have C, U, R, F checked as notification options.

By selecting the S option you will get the notify of the start and end of the Scheduled downtime event.
