Nagios Support Forum

Hi,
I've a little problem with the configuration of sending mail alerts to contacts...
Nagios Xi contacts don't receive mail alerts from Nagios.
Sending mail alerts to Nagios Xi users and admins work good !
I feel that Nagios is not going to read my contacts.cfg...
Can s.o. help me ? Thx

A few questions:
1) What notification handlers are configured on the core contacts?
2) Do you use SMTP or Sendmail to send notifications?

1) xi_host_notification_handler / xi_service_notification_handler
2) SMTP

Core contacts cannot use the xi_*_notification_handler 's as they do not have entries in the postgres db. Using smtp with core contacts and the old notify-*-by-email handlers is a bit tricky, but can be done. Does your smtp relay use auth?

Should I use notify-*-by-email ?
My SMTP work without authentication

I would suggest changing the core contacts (contacts without associated XI users) to the notify-*-by-email commands. If they do not send correctly, we will have to look at creating some core notify commands for connecting to an smtp relay.

I've created a Core contact with notify-*-by-email

define contact {
contact_name test
alias Test User
host_notifications_enabled 1
service_notifications_enabled 1
host_notification_period 24x7
service_notification_period 24x7
host_notification_options d,u,r,f,s,
service_notification_options w,u,c,r,f,s,
host_notification_commands notify-service-by-email
service_notification_commands notify-service-by-email
email [email protected]
use generic-contact
}

I'm not receiving Nagios mail alerts...

Is there a specific reason you have both the host and service notifications set to use the service notification handler? The email should still go out but it would have some problems.

Can we see your mail log? I want to see if Nagios is at least attempting to send.

tail -20 /var/log/messages

Be sure to censor out any sensitive information.

I've both the host and service notifications to receive alerts for hosts and services problems...

Looks like, for nagiosadmin at least, that you are using "xi_service_notification_handler." What Abrist was referencing in the last post was that you had "notify-service-by-email" also defined for your host notifications on that contact. So you would essentially receive no host notifications via it. You also need to make sure to assign your contacts to the objects they are responsible for, hosts/services, or they will not receive notifications. You can either assign them directly or use a contact group.
