I am running Nagios XI on RHEL5.

I have enabled notifications globally.

## /usr/local/nagios/etc/nagios.cfg
...
enable_notifications=1
# ...

I have enabled notifications for my device and service template:

Code: Select all

# /usr/local/nagios/etc/static/templates/host.cfg
define host {
       name                                     ctv-server
       use                                      linux-server
       contact_groups                           ctvadmins
       notifications_enabled                    1
       register                                 0
}

define service {
       name                                     ctv-service
       use                                      local-service
       contact_groups                           ctvadmins
       notifications_enabled                    1
       register                                 0
}

I have configured the contacts with specific notifications:

Code: Select all

define contact {
        contact_name                            ctvadmin
        alias                                   C TV Administrator
        host_notification_period                ctvadmin_notification_times
        service_notification_period             ctvadmin_notification_times
        host_notification_options               d,u,r,f,s
        service_notification_options            w,u,c,r,f,s
        host_notification_commands              notify-host-by-email
        service_notification_commands           notify-service-by-email
        email                                   [email protected]
        use                                     xi_contact_generic
        }


define contactgroup {
        contactgroup_name                       ctvadmins
        alias                                   C TV Administrators
        members                                 ctvadmin
        }

The test email from nagios XI console succeeds.

Yet, I do not see notifications issued when a host or a service goes down.
I see the following messages in /usr/local/nagios/var/nagios/log:

Code: Select all

# tail -f /usr/local/nagios/var/nagios.log
//...
[1370120018] SERVICE NOTIFICATION: ctvadmin;ctv-xjabprd-2;Jabber CM1;CRITICAL;notify-service-by-email;CRITICAL - Socket timeout after 10 seconds

which seems to indicate that the notification was initiated - I do not see the email in my inbox.
How do I troubleshoot this?

thanks

The "notification settings" page in Nagios XI says that the feature is only
available in the enterprise edition (I am running an eval version):

I assume this restriction applies only to the notification settings page of Nagios XI
and not to notifications themselves, which is a part of Nagios core.

pl help

I notice in /var/log/maillog that

Code: Select all

(in reply to MAIL FROM command))

However, I have a valid settings in Admin -> Manage Email Settings:

Where does it obtain the email settings from?

XI send email through the phpmailer function. The settings are a combination of what you enter in the "manage email settings" page and the XI server's hostname.

This error message seems to imply that your nagios xi server is lacking an FQDN, and your smtp server requires it. Try changing your XI server's hostname to an FQDN, or talk to your email admin to have the restrictions loosened for mail coming from the XI server.
