What version of Nagios XI is this? And do you mean alerts for Windows hosts/services are working but alerts for AIX hosts/services are not?

Hi tmcdonald,

Yes mails are configured with proxy setting in nagiosxi system. We are able to receive mails from windows system as well as suse linux systems. but AIX, we are not able to receive mails in our mail box.

We are using NagiosXI 2014 R1.3. In half of the AIX systems we have more than 50 disk partitions and we have configured them in nagiosxi for warning and alert.

One more thing i want to mention here, in /usr/local/nagios/etc/hosts and /usr/local/nagios/etc/services--> when we are giving apply configuration for any update this AIX system files are not updating (with time stamps) all files are changing their times in specified hosts and services folder.

let me clear more:
when we are apply any configuration all files which is hosts files in /usr/local/nagios/etc/hosts/ and /usr/local/nagios/etc/services/ should be update. but except AIX system files all files updating. means when we checked in specified folders times changed for all hosts except AIX servers.

Thanks in advance

What types of reports are you running for how long of a time interval? 50 partitions = 50rrds. With a long enough time period for the report and slow disk io/heavy usage may cause the report to time out.

when we are apply any configuration all files which is hosts files in /usr/local/nagios/etc/hosts/ and /usr/local/nagios/etc/services/ should be update. but except AIX system files all files updating. means when we checked in specified folders times changed for all hosts except AIX servers.

The behavior for apply config changed in 2014. It no longer writes all config files out, just those that have changed in the CCM since the last write out. This drastically reduces the apply config time. If you are noticing changes in the CCM are no longer getting written out, you may have a time mismatch between the system and mysql. Verify the system time and then restart mysql to sync it to the system time.

1) What notification handlers are your contacts/users using?
2) What email method are you using? sendmail or smtp?
3) You may find the following document of interest as it will outline the differences between the core and xi notification handlers, core contacts and xi users, and sendmail vs smtp (phpmailer):
http://assets.nagios.com/downloads/nagi ... ntacts.pdf
And some definitions:

A Few Definitions
Core Contact:
A contact created through the CCM or imported from a text config.

XI User Contact:
A contact created through the "Add New User" Admin interface by checking the box labeled "Create as a Monitoring Contact".

Core Notification Handlers:
Nagios Core notification commands - "notify-host-by-email" and "notify-service-by-email". The handlers use sendmail
exclusively and will not work with the XI SMTP settings.

XI Notification Handlers:
Nagios XI notification commands - "xi_host_notification_handler" and "xi_service_notification_handler". These handlers
use the Nagios XI SMTP settings but require that the contact was created as an XI User Contact.

Sendmail:
A linux binary that sends mail. By default, Core contact notification handlers use sendmail.

Phpmailer (SMTP):
The library that XI uses to send mail using the settings from the "Manage Email Settings" Admin interface – it includes support
for SMTP relays.

A Few Notes Concerning Notification Methods

Contacts can be configured in two different way in XI. The first method is to create an XI user as a monitoring contact by checking the
"Create as Monitoring Contact" checkbox from the "Add New User" interface (Admin → Manage Users → Add New User). Creating a
contact using this method will link the contact to the XI User. This provides the contact with the configuration from the User Settings
and more importantly allows the contact to use the XI host and services notification handlers. This is important to those environments
that use an SMTP relay server as XI's email configuration usually requires the XI notification handlers in order to send mail using the
phpmailer SMTP options.

The second method to create contacts is by creating a new contact through the CCM. Contacts created this way will not be associated
to an XI user and by default, will not work with the XI notification handlers nor the SMTP server settings in the "Manage Email Settings"
interface. Core contacts, by default, will only work with the sendmail option.
