Nagios Core - Problem with E-Mail Notifications

[rkennedy]

Looks like it's still set at that (root@localhost). Please PM your /usr/local/nagios/var/objects.cache file for me to look at.

Last thing, Nagios Core don't need the "E-Mail Configuration" (Pop Server, Smtp Server, Authentication credentials) for sending the E-Mail?

No, it uses the basic mail sending on your machine. Was there a specific reason you switched from Nagios XI?

You'll want to modify your contact definition to be accurate, and not have the email set to nagios@localhost -

Code: Select all

define contact {
	contact_name	nagiosadmin
	alias	Nagios Admin
	service_notification_period	24x7
	host_notification_period	24x7
	service_notification_options	r,w,u,c,f,s
	host_notification_options	r,d,u,f,s
	service_notification_commands	notify-service-by-email
	host_notification_commands	notify-host-by-email
	email	nagios@localhost
	minimum_importance	0
	host_notifications_enabled	1
	service_notifications_enabled	1
	can_submit_commands	1
	retain_status_information	1
	retain_nonstatus_information	1
	}

The Problem was that in the Contacts files there was a duplicate "notify-host-email". Don't know why nagios didn't tell me that before.

By the way, there is a way to DISABLE only the "Recovery" E-Mails? I need only the Warning - Critical E-Mails.

You'll want to remove the -r flag from your definition. See this -

notification_options: This directive is used to determine when notifications for the host should be sent out. Valid options are a combination of one or more of the following: d = send notifications on a DOWN state, u = send notifications on an UNREACHABLE state, r = send notifications on recoveries (OK state), f = send notifications when the host starts and stops flapping, and s = send notifications when scheduled downtime starts and ends. If you specify n (none) as an option, no host notifications will be sent out. If you do not specify any notification options, Nagios will assume that you want notifications to be sent out for all possible states. Example: If you specify d,r in this field, notifications will only be sent out when the host goes DOWN and when it recovers from a DOWN state.

I resolved this, thank you. We can close the thread.

Awesome! Closing this out.
